Compound A has a parent peak of M+ = 95 m/z in its mass spectrum and shows a medium intensity sharp infrared absorption band at 2280 cm. The HNMR of compound A shows 3 signals in a 4:4:1 ratio. Treatment of compound A with hot aqueous acid generates compound B (M+= 113 m/z) can be transformed back to A by using SoCl2. Finally compound B can be transformed with lithium aluminum hydride (ether) then aqueous acid to compound C (M+ = 99 m/z). What are A, B, and C
