• # question_answer Which of the following has a bond formed by overlap of $sp-s{{p}^{3}}$ hybrid orbitals [MNR 1993; UPSEAT 2001, 02] A) $C{{H}_{3}}-C\equiv C-H$ B) $C{{H}_{3}}-CH=CH-C{{H}_{3}}$ C) $C{{H}_{2}}=CH-CH=C{{H}_{2}}$ D) $HC\equiv CH$

$\underset{s{{p}^{3}}}{\mathop{C{{H}_{3}}}}\,-\underset{sp}{\mathop{C}}\,\equiv \underset{sp\,\,\,\,\,\,\,\,\,\,\,}{\mathop{C-H}}\,$
