Question

Arrange the following compounds in increasing order of their boiling points. I. CH3 CH2 CH2Br II . CH3CH2CH2CH2Br III. (CH3)2CHCH2Br IV. (CH3)3 CBr (A) II < I < III < IV (B) III < I < IV < II (C) IV < III < II < I (D) I < IV < III < II

Tardigrade Admin · Accepted Answer

Boiling points increase as the number of carbon atoms in the alkyl halide increases. Therefore, the boiling points of II, III and IV with four carbon atoms is higher than that of I with three carbon atoms. Further, the boiling points decrease with the number of branches. Thus, the boiling points of the four alkyl halides increase in the order: I < IV < III < II
