Question

A hydrocarbon A, with the formula C₈H₁₀, on ozonolysis gives compound B (C₄H₆O₂) only. The compound B can also be obtained from the alkyl bromide C (C₃H₅Br) upon treatment with magnesium in dry ether, followed by carbon dioxide and acidification. Give the number of secondary hydrogen atoms in compound A.

Options:
a. 6
b. 8
c. 10
d. 12

Answer 1

The hydrocarbon A, with the formula C8H10, is an octene that does not contain any secondary hydrogen atoms. Therefore, the correct option is C.

Step-by-step explanation:

The hydrocarbon A, with the formula C8H10, is an octene. When it undergoes ozonolysis, it produces compound B, C4H6O2. The fact that compound B can also be obtained from the alkyl bromide C, C3H5Br, indicates that it is an ester. In order to determine the number of secondary hydrogen atoms in compound A, we need to consider its structure. Since compound A is an octene, it contains a double bond. The presence of a double bond means that there are no secondary hydrogen atoms in the molecule. Therefore, the correct answer is option c. 10.
