CS₂ is non-polar, non-ionisable solvent and produce only para substituted compound due to the production of less Br⁺ ion, while H₂O itself a polar solvent and produce sufficient concentration of Br⁺ to attack on ortho and para position.

What is the cutoff 2025 for BFA at Allahabad University?

Contributor-Level 10

From (II), 40% of total number of students = 96

Total number of students = (96/40)*100=240

Number of boys = 240 – 96 = 144

From (I), number of average male students =144/3=48

From (III), number of excellent students = 240/2= 120

Number of excellent female = 120 – 50 = 70

From these calculations, we get the following table.

	Performance			Total
	Average	Good	Excellent	Total
Male	48	46	50	144
Female	18	8	70	96
Total	66	54	120	240

From the above table, it is clear that number of male good students = 46

Has the MBBS cutoff at JNMC increased in recent years?

Contributor-Level 10

Electronic configuration of $O_{2}^{-}$ anion is;

${(σ 1 s)}^{2} {(σ_{1 s}^{*})}^{2} {(σ_{2 s})}^{2} {(σ_{2 s}^{*})}^{2} {(σ 2 p z)}^{2} {(π 2 p x)}^{2} = {(π 2 p y)}^{2} {(π * 2 p x)}^{2} = {(π * 2 p y)}^{1}$

In anion total 10 e^- resides in Bonding Molecular Orbitals and 7e^- resides in anti-Bonding Molecular orbitals. Hence bond order $= \frac{10 - 7}{2} = \frac{3}{2} = 1.5 .$

It is paramagnetic due to one unpaired electron.

Yes, the MBBS cutoff at JNMC has consistently increased. In 2023, the closing rank was 4833, and it improved to 3752 in 2024. This trend indicates growing interest in the college and suggests that students will likely need stronger NEET scores for 2025 admission.

Mr. John has 5 children & he gives different pocket money to all of his 5 children to do 5 particular tasks viz. going for morning walk, Exercise, Completing their home work, Drinking Milk and Assisting in family work. A particular child can do only one task at a time and each task can be assigned to one child only. (The values are in $)

Children	1	2	3	4	5
Going for Morning Walk	35	31	44	23	36
Exercise	48	42	57	35	37
Completing their Homework	28	55	52	38	44
Drinking Milk	55	21	26	37	42
Assisting in Family work	26	35	34	51	47

If all the children increase the pocket money demanded by them for the tasks, then what will be the least amount for doing the task, keeping in mind that children 1, 2, 3, 4 and 5 increased the amount for the task by 50%?

The answer can be obtained directly by increasing the answer in question 11 by 50%, as all the Children increase the cost by 50% and hence the total cost will increase by 50% only.

Heavy water (D₂O) is used to study reaction mechanism. O-H bond energy is less than O-D, hence it will produce fast reaction than O-D. Here assertion is true but Reason is false.

For this we need to maximize the cost each of the task, then we will find the maximum cost.

Maximum Cost = $36 (Child 5 doing Going for Morning walk) + $57 (Child 3 doing Exercise) + $55 (Child 2 doing home work) + $55 (Child 1 drink Milk) + $51 (Child 4 family work) = $254
