Question

Cis-3,4-dimethylcyclobutene undergoes photochemical ring opening take place by

A

Disrotatory motion

Conrotatory motion

B

Clockwise

None of the above​

Answer 1

Answer:

A disrotatory motion

conrotaroy motion

Answer 2

Answer:

option(A)- Disrotatory motion

Explanation:

• Based on the rotation at every cease of the molecule, an electrocyclic procedure may be classified as conrotatory or disrotatory.

• The cease groups' atomic orbitals revolve withinside the equal path in conrotatory mode (together with each atomic orbitals rotating clockwise or counter-clockwise).

• End organization atomic orbitals flip in contrary instructions withinside the disrotatory way (one atomic orbital turns clockwise and the opposite counter-clockwise). The distinction between connotation and disrotation determines the cease product's cis/trans geometry.
