Question 1:

Which type of isomerism is exhibited by the compounds CH3CH2OH and CH3OCH3?

Explanation: The correct answer is A) Structural isomerism. The compounds CH3CH2OH (ethanol) and CH3OCH3 (methoxymethane) have the same molecular formula but differ in the arrangement of atoms, exhibiting structural isomerism.

Question 2:

Which type of isomerism is exhibited by the compounds CH3CH=CHCH3 and CH3CH(CH3)CH3?

Explanation: The correct answer is A) Structural isomerism. The compounds CH3CH=CHCH3 (1-butene) and CH3CH(CH3)CH3 (2-methylpropane) have the same molecular formula but differ in the arrangement of atoms, exhibiting structural isomerism.

Question 3:

Which type of isomerism is exhibited by the compounds CH3CHClCH3 and CH3CH(CH3)CH2Cl?

Explanation: The correct answer is A) Structural isomerism. The compounds CH3CHClCH3 (1-chloropropane) and CH3CH(CH3)CH2Cl (2-chloropropane) have the same molecular formula but differ in the arrangement of atoms, exhibiting structural isomerism.

Question 4:

Which type of isomerism is exhibited by the compounds CHFClBr and CHClBrF?

Explanation: The correct answer is A) Structural isomerism. The compounds CHFClBr and CHClBrF have the same molecular formula but differ in the arrangement of atoms, exhibiting structural isomerism.

Question 5:

Which type of isomerism is exhibited by the compounds CH3CH2CH(CH3)CH2CH3 and (CH3)3CCH2CH2CH3?

Explanation: The correct answer is A) Structural isomerism. The compounds CH3CH2CH(CH3)CH2CH3 (2-methylhexane) and (CH3)3CCH2CH2CH3 (2,2-dimethylpentane) have the same molecular formula but differ in the arrangement of atoms, exhibiting structural isomerism.
