The Total solution for NCERT class 6-12
Thehybridization state of carbon in these three compounds is:Since s-electrons are closer to the nucleus, therefore, as the s-character ofthe orbital making the C—H bond increases, the electrons of C—H bond lie closerand closer to the carbon atom. In other words, the partial +ve charge on theH-atom and hence the acidic character increases as the s-character of the orbitalincreases. Thus, the acidic character decreases in the order: Ethyne >Benzene > Hexane
