Question
Chapter 3, Problem 49SA
Summary Introduction
To review:
The capability of chloroform (HCCl3) molecule to form weak hydrogen bonds.
Introduction:
A hydrogen bond is formed between a hydrogen atom and a highly electronegative atom (like nitrogen, oxyge, nnd fluorine). A lone pair of electrons on an adjacent atom (involved in the bond formation) is also required for hydrogen bonding.
