4.23. The dipole moment of NH₃ (1.47D) is higher than the dipole moment of NF₃ (0.24D), even though the molecular geometry is pyramidal for both the molecules. In each molecule, N atom has one lone pair. F is more electronegative than H and N? F bond is more polar than N? H bond. Hence, NF₃? is expected to have much larger dipole moment than NH₃. However, reverse is true. In case of ammonia, the direction of the lone pair dipole moment and the bond pair dipole moment is same whereas in case of NF₃, it is opposite. Thus, in ammonia molecule, individual dipole moment vectors add whereas in NF₃, they cancel each other.

Candidates often get confused which college to get admission in. For GNM college selection, students can opt for Impact Paramedical and Health Institute. The institute GNM course tuition fees is INR 2.7 lakh. It is also affiliated with the Delhi Nursing Council (DNC). 

Students have other college preferences can compare this institute with other similar institutes. A few parameters that can be considered for the college comparison are fees, placements, faculty, and more.

11.9  Phenol on mixing with chloroform and NaOH at 340K followed by Acidic hydrolysis, salicyl aldehyde is formed. When carbon tetrachloride (CCl₄) is used at the place of chloroform salicylic acid is This type of reaction is known as Reimer - Tiemann reaction.

2. The sodium phenoxide reacts with CO₂ under pressure 4-7 atm at a 400K temperature to form sodium salicylate, which on acidification yields salicylic acid. This type of reaction is known as Kolbe's

Yes, Dr. Shakuntala Misra National Rehabilitation University (DSMNRU) does provide scholarships for its BCom courses. The university offers national and state government scholarships through schemes like the National Handicapped Finance and Development Corporation and the State Government Scholarship scheme. Students who are eligible to be awarded a scholarship can apply for these through the university or the respective government website.

4.22. BeH₂is a linear molecular (H—Be—H), the bond angle = 180°. Be—H bonds are polar due to difference in their electronegativity but the bond polarities cancel each other. Thus, molecule has resultant dipole moment of zero

There are over 50 colleges in Delhi that offers GNM courses apart from Impact Paramedical and Health Institute. The UG course at the IPHI Delhi is a three-year course of full-time mode. Mentioned below are a few other colleges in Delhi that offers GNM:

• Metro College of Nursing
• Gandhi College of Nursing
• NIMT

• Brahm Shakti School of Nursing, etc.

Sumandeep Vidyapeeth offers 100 seats in the BSc Nursing programme. Candidates applying for admission into the programme should make sure they have cleared the eligibility criteria for BSc admission at the institute. For admission into BSc Nursing, candidates will need to have a minimum aggregate of 35% to be eligible for admission into the course.

4.21. According to VSEPR theory, if CH₄ were square planar, the bond angle would be 90°. For tetrahedral structure, the bond angle is 109°28? Therefore, in square planar structure, repulsion between bond pairs would be more and thus the stability will be less.

Moreover, the orbitals of carbon in ground and excited states look as shown below. In the excited state, the electrons from 4 H atoms occupy one 2s orbital and three 2p orbitals. This results in an sp³ hybridisation, which is the hybridisation of a tetrahedral geometry

CII Institute of Hospitality, Taj Mehal, Lucknow fee ranges between INR 4.9 Lacs and INR 5.2 lakh. Candidates must pay the course fee at the time of admission for the final seat confirmation in the programme.

Yes, students are generally permitted to carry and use mobile phones in the hostels at NIT Trichy. However, there are restrictions on their use within the academic zone (classrooms). The institute also provides superfast Wi-Fi in all hostel zones. But I request you to decrese your phone usage for your academic exellence. over using of phone may leads to decrease in your visual, hearing etc. 

The candidates may take different parameters into consideration to ascertain whether a university or an institute would be a preferable option to DSMNRU for completing BCom. The parameters include tuition fees, hostel fees, number of specialisations provided, selection process, geographical location, placement report, ROI, and so on. These parameters enable the candidates to judge which institute or university is preferable for choosing the BCom course.

From the available informations Visva Bharati University's M.Sc. Chemistry programme through CUET PG, expected cut-off scores are around 190-210 for the General category and 160-180 for the ST category. However, it's crucial to note that these are just expected ranges, and the actual cut-off may vary based on factors like the number of applicants and their scores. cutoff are change every year. cut marks can be decided by the authorities based on the perfomance of candidates in that year.

4.19. N₂ < SO₂ < ClF₃ < K₂O

The ionic character in a molecule is dependent upon the electronegativity difference between the constituting atoms. The greater the difference, the greater will be the ionic character of the molecule.
