Stem nouncement Problem 14.34 A compound (L) with the molecular formula 10 reacts with br in carbon tetrachloride and gives an IR absorption 740 cm i(s), 695 cm-1(s). The 1H NMR spectrum of L consists of: Doublet 6 3.1 (2H) Multiplet 55.1 Multiplet 7.1 (5H) Multiplet 64.8 Multiplet 5.8 The uv spectrum shows a maximum at 25s nm. propose a structure for compound L.

Explanation / Answer

14.34. The spectrum of L is given

formula of L = C9H10

degree of unsaturation = 5

after bromination gives one multiplet at 7.1 for 5 H due to phenyl protons.

Possible structure,

C6H5-CH(Br)-CH2-CH2-Br

The CH2 protons between CH(Br) and CH2(Br) splits into two peaks.
