• # question_answer Which of the following is most likely to show optical isomerism [UPSEAT 2004] A) $HC\equiv C-\underset{Cl\,}{\overset{H\,}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,-}}}\,C\equiv CH$ B) $HC\equiv C-\underset{Cl}{\overset{H}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-C{{H}_{3}}$ C) $HC\equiv C-\underset{Cl}{\overset{H}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-H$ D) $HC\equiv C-\overset{Cl}{\mathop{\overset{|}{\mathop{C}}\,}}\,=C{{H}_{2}}$

Solution :

$HC\equiv C-\underset{Cl\ }{\mathop{\overset{H}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}\,-}}\,C{{H}_{3}}$ shows optical isomerism because of molecule is unsymmetrical. That is called chiral.
