5.	match the column (I) and (II).
Answer» Solution :The chair conformer with methyl substituent in an equatorial position is more stable because a substituent has more room and, therefore, fewer steric interactions when it is in an equatorial position. When the methyl group is in an equatorial position, it is anti to the C-3 and C-5 carbons (FIGURE). Therefore, the substituent extends into space away from the REST of the molecule. In constrast, when the methyl group is in an axial position, it is gauche to the C-3 and C-5 carbons (fig.) As a result, there are unfavourble steric interactions between the axial methyl group and both the axias substituent on C-3 and the axial substituent of C-5 (in this case HYDROGENS). In other words, the three axial bonds on the same side of the ring are parallel to each carbons. Because the interacting substituents are on 1,3-positions relative to each other,these unfavourable steric interactions are called 1,3-diaxial interactions `*` Alkyl group ocupy equational position to achieve maximum stability. `*` If the size of alkyl group increase, then stability of conformer will increase and VALUE of equilibrium constant will also increase.

35.	Match the column
Answer» Solution :(A). It is a mercuration demercuration REACTION, FORMATION of alcohol TAKES place according to mark-ovnikov's rule. The first step of this reaction addition of electrophile `AcOoverset(o+)(H)g` to `(C=C)` bond to form mercurinium ions, is stereospecific, but the second step, addition of `H^(+)` from `NaBH_(4)`, is not clearly stereospecific. so, OVERALL the reaction is non-stereospecific. (B). It is an alkoxy mercuratio demercuration reaction, which proceeds with a similar mechanisms as i (A) (C). It is hydroboration oxidation (HBO) reaction. the formatio of alcohol takes place with anti markovnikov's rule with syn-addition. the overall reaction is stereospecific. (D). It is also an `HBO` REACTIO involving the formation of cis-alkene and proceeds with the similar mechanisms as in (C).
