Question

-CH2CH2CL. AND -CH2CH(CH3)2 which one has higher priority in S and R configuration can anyone please explain with reason​

Answer 1

Answer:

In structure II, the two highest-priority atoms are the opposite sides of the double bond (above and below it), so this is named as the E-isomer. ... With CH2CH3, we have a second C (and its attached H atoms). Since C has a higher atomic number than H, then CH2CH3 takes priority over
