Answer 1

1. The general formula of alkane is . So option I is the correct answer.

3. To achieve noble gas configuration, hydrogen requires Duet where as Chlorine requires Octet. So option c is the right answer.

5. The other name of Methylbenzene is toluene. So option IV is the correct answer.

7.The name of the compound is 4-aminobutanoic acid.So option V is right answer.

8.Benzoyl chloride is an example of Alicyclic acid chloride. So option II is correct answer.
