Question

A hydrocarbon X has molecular formula C8H18 Substitution of a hydrogen of X by bromine atom gives one single bromoalkane. Hence, compound X is (A) 2,2, 3, 3-tetramethylbutane (B) diethyl pentane (C) 2, 3 ,4-trimethylpentane (D) 2, 5-dimethylhexane

All hydrogens are equivalent, hence substitution of any of the 18 hydrogens would yield the same, 1-bromo-2, 2,3 ,3-tetramethyl butane <img class="img-fluid question-image" alt="image" src="https://cdn.tardigrade.in/img/question/chemistry/344096284660951f998da342a0cd37c9-.png" />

Q. A hydrocarbon X has molecular formula $C_{8} H_{18}$ Substitution of a hydrogen of X by bromine atom gives one single bromoalkane. Hence, compound X is

$2, 2, 3, 3$ -tetramethylbutane

diethyl pentane

$2, 3, 4$ -trimethylpentane

$2, 5$ -dimethylhexane
