Explain, illustrating with a mechanism.
- Explain why CH3CH2CH2CH2Cl reacts with 0.01M NaCN in Ethanol (C2H5OH) to yield primarily CH2CH2CH2CH2CN, whereas under the same conditions, (CH3)3CCI reacts to give primarily (CH3)3COCH2CH3.Suggest a possible reason for the following observations: (i) The order of reactivity of haloalkanes is RI > RCl > RBr.

Determine the structure of B from its 1H NMR and IR spectra.(10pts) Compound A, C10H16, was found to be optically active. On catalytic reduction over a palladium catalyst, 2 equivalents of hydrogen were absorbed, yielding compound B, CioH2o. On ozonolysis of A, two fragments were obtained. One fragment was identified as acetic acid (CHCOOH). The other fragment, compound C, was an optically active carboxylic acid, C8H14O2. Write reactions, and draw the correct structures for A-C, explain your answer in detail.Consider the reaction between (1S,3S)‑1‑chloro‑3‑methylcyclopentane and methanethiol in the presence of sodium hydroxide.
