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

    Answer:

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