• # question_answer 32) What is the total number of sigma and pi bonds in the following molecules? (a) ${{C}_{2}}{{H}_{2}}$ (b) ${{C}_{2}}{{H}_{4}}$

$\underset{\text{(3}\sigma \text{+2}\pi \text{) bonds}}{\mathop{H-C\equiv C-H}}\,$ $\underset{\text{(5}\sigma \text{+1}\pi \text{) bonds}}{\mathop{_{H/}^{H\backslash }C=C_{\backslash H}^{/H}}}\,$
