There are four isomers with molecular formula C4H9CI. Only one of these isomers

There are four isomers with molecular formula C4H9CI. Only one of these isomers (compound A) has a chirality center. When com- pound A is treated with sodium ethoxide, three products are formed: compounds B, C, and D. Compounds B and C are diastereomers, with compound B being the less stable diastereomer. Do you expect compound D to exhibit a signal at approximately 1650 cm in its IR spectrum? Explain.
