which compound contains both sigma and pi bonds?\n○ hccl3\n○ h2co\n○ h2s\n○ hbr
Answer
Brief Explanations:
Sigma bonds are formed by head - on overlap of orbitals and are present in all single bonds. Pi bonds are formed by side - on overlap and are present in double and triple bonds.
- In $HCCl_3$, all bonds are single bonds, so it has only sigma bonds.
- In $H_2CO$, there is a $C = O$ double bond. A double bond consists of one sigma and one pi bond, along with the $C - H$ single (sigma) bonds.
- In $H_2S$, all bonds are single bonds, so it has only sigma bonds.
- In $HBr$, it has a single bond, so it has only sigma bonds.
Answer:
B. $H_2CO$
