Solution:
(a) $ \underset{s{{p}^{2}}}{\mathop{{{H}_{2}}C}}\,=\underset{s{{p}^{2}}}{\mathop{CH}}\,=\underset{sp}{\mathop{C}}\,\equiv \underset{sp}{\mathop{N}}\, $ (b) $ \underset{sp}{\mathop{HC}}\,\equiv \underset{sp}{\mathop{C}}\,-\underset{sp}{\mathop{C}}\,\equiv \underset{sp}{\mathop{CH}}\, $ (c) $ \underset{s{{p}^{2}}}{\mathop{{{H}_{2}}C}}\,=\underset{sp}{\mathop{C}}\,=\underset{sp}{\mathop{C}}\,=\underset{s{{p}^{2}}}{\mathop{C{{H}_{2}}}}\, $ (d)
Hence, $ {{H}_{2}}C=CH-C\equiv N $ represents the $ s{{p}^{2}}-s{{p}^{2}}-sp-sp $ hybridisation from left to right.
