Phenol is prepared by:

Dow’s process: The chlorobenzene on heating with NaOH, form sodium phenoxide which on hydrolysis with water of acid from phenol.

Diazotization of aniline: Aniline on reacting with nitrous acid at 0-5^o C followed by hydrolysis with water form phenol.

Benzene undergoes sulphonation on reacting with oleum to form benzene sulphonic acid which on heating with sodium hydroxide forms sodium phenoxide and then phenol on hydrolysis.

The nucleophilic substitution of haloarenes such as chlorobenzene requires drastic conditions for conversion to phenol so chlorobenzene will not be converted to phenol on heating with NaOH at 298K / 1atm.

(I) Propan- 1-ol. butan-2-ol. butan- 1-ol. pentan- 1-ol 

The compounds Propan-l-ol, butan-2-ol, butan-1-ol, pentan-1-ol belong to the alcohol family. The structure of the given  alcohols are as shown below:

With increase in the molecular weight, the boiling points of alcohols increase. Hence, butan-1-ol has higher boiling point than propan-1-ol. Similarly, pentan-1-ol has higher boiling point than butan-1-ol.

Hence, the increasing order of the boiling points of alcohols is propan-1-ol < butan-1-ol < pentan-1-ol.

With increase in the branching of alkyl groups, the boiling point of alcohols decreases. Thus, butan-2-ol has lower boiling point than butan-1-ol. The increasing order of the boiling points of given alcohols is

The difficulty level of MBOSE SSLC board exams can vary from year to year. It depends on several factors, including the individual student's preparation, the specific subjects, and the exam format.

Generally, students find the following points relevant when assessing the toughness of MBOSE SSLC board papers:

1. Question Format: The papers often include a mix of objective, short answer, and long answer questions. Students need to be well-prepared for all types of questions.
2. Previous Year Trends: Some students find that the difficulty level of the papers is in line with previous years, while others may find unexpected questions. Reviewing past papers can help gauge the expected difficulty.
3. Subject Variability: Subjects like Mathematics and Physics are often considered more challenging compared to subjects like English or History, depending on the student's strengths and interests.
4. Syllabus Coverage: The syllabus for Class 10 is extensive, and students are expected to have a deep understanding of the concepts. This can make the exams challenging if students do not cover the syllabus thoroughly.
5. Preparation Strategies: Effective study habits, time management, and practice with sample papers can significantly influence students' perceptions of the exam's difficulty.

So, whether the MBOSE Class 10 board exam is tough or not depends on individual preparation and strengths in specific subjects. Students are encouraged to study thoroughly and practice regularly to build confidence and improve their performance.
