Draw the zaitsev product formed when 2,3-dimethylpentan-3-ol undergoes an e1 dehydration.

Zaitsev product formed when undergoes dehydration is drawn in the attached image.

Further Explanation:

In the elimination reaction, a pair of groups are eliminated from the molecule by a dehydrating agent such as or . Removal of either an alkyl halide or water molecule may occur ant it results in formation of an alkene. The formation of major and minor alkene is governed by the Hoffman rule or Zaitsev rule.

There are two kinds of elimination reactions namely E1 and E2. The unimolecular elimination reactions proceed through two steps that involve carbocation formation and rearrangement. The product is governed by the pathway that leads to more stable carbocation.

Zaitsev rule says that a formation of a more substituted alkene is more favored in an elimination reaction while the Hoffman rule predicts that a least substituted alkene is more favored if the alkene is formed from asymmetrically amines such as quaternary ammonium salt.

The usual dehydration reaction of alcohol follows the Zaitsev rule. More substituted alkene is the major product formed from the elimination of water from . (Refer to the attached image).

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
