• question_answer The bond between carbon atom (1) and carbon atom (2) in compound $N\equiv C-CH=C{{H}_{2}}$ involves the hybridised carbon as [IIT-JEE 1987; DCE 2000] A) $s{{p}^{2}}$ and $s{{p}^{2}}$ B) $s{{p}^{3}}$ and $sp$ C) $sp$ and $s{{p}^{2}}$ D) $sp$ and $sp$

sp and $s{{p}^{2}}$ $N\equiv \overset{sp}{\mathop{\underset{1}{\mathop{C}}\,}}\,-\underset{2}{\overset{s{{p}^{2}}}{\mathop{CH}}}\,=\underset{3}{\mathop{C{{H}_{2}}}}\,$
