A) \[C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-Cl\left( pyridene \right)\]
B) \[C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-OH\left( {{H}_{2}}S{{O}_{4}} \right)\]
C) \[C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-O-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-C{{H}_{3}}\left( pyridene \right)\]
D) \[C{{H}_{3}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-H\left( {{H}_{2}}S{{O}_{4}} \right)\]
Correct Answer: D
Solution :
[d] Acid chlorides, anhydrides, acids give ester with alcohol \[ROH+R'COCI\xrightarrow{{}}ROCOR'+HCl\] \[ROH+{{\left( R'CO \right)}_{2}}O\xrightarrow{{}}ROCOR'+RCOOH\] \[ROH+{R}'COOH\xrightarrow{{}}ROCO{R}'+{{H}_{2}}O\]
