Cho vs ch2oh cahn ingold
WebAug 17, 2024 · It is because of this rule, that the second carbon of CH 2 gets a lead over the CH 3 branch. If -CH 3 (order no 3) was to be given priority over -CH 2 CH 3 (order no 2), it would be against this rule of Cahn Ingold Prelog priority rules, and the compound would have been ‘R’ configured.
