CH3-CH-CH2Br

The central carbon has the free radical and it is a secondary radical.
The two other carbons one on left and other on right - both are alpha carbons to the central carbon.

These two alpha carbons having hydrogen attached to them are called alpha hydrogens. The total number of alpha hydrogens = 3 +2 = 5

nid16: but bromine is attached to one of the carbon atoms. So why can't that carbon (to which br is attached) be the alpha carbon?
arumairajppbnso8: Be clear with your question.
arumairajppbnso8: You need the alpha hydrogen w.r.t bromine or w.r.t free radical carbon?
nid16: so.. if we con consider with respect to bromine then the no. of Alpha hydrogen will be 1 and if we consider with respect to free radical then the number of Alpha hydrogens will be 5
nid16: am i right?
arumairajppbnso8: Yes. Hope you are clear.
nid16: Yes. It's clear. Thank you so much. :)
