    2 -methylbutane an monochlorination gives 4 isomers, among which I and lll are chiral in nature. Hence, 2 chiral compounds are formed in the above reaction. 2 enantiomers also of these two chiral compounds so correct answer is 4 chiral compound.

    eduncle-logo-app

    but sir greater the ring size greater the + I effect ..so basicity increased na in d

    eduncle-logo-app

    yes but experimentaly it is found that 5 member amine are more basic than 6 members

    eduncle-logo-app

    because 3 CH3 groups give +I and also the l.p is available so basicity increases na

    eduncle-logo-app

    what is givem in your booklet.

    eduncle-logo-app

    option A is correct because of resonance

    eduncle-logo-app

    option A but sir here delocalisation of l.p happens so basicity decreases na
