non-ionic detergents can be made by reaction of epoxyethane,in an excess,with a C11 alcohol.

A possible mechanism involves homolytic fission of a C-O bond in epoxyethane giving rise to a double ended free radical that initiates a chain reaction.The first propagation step is as follows:

.CH2-CH2-O +epoxyethane (H2C-CH2-O where this O is linked backed to CH2) -- .CH2-CH2-O-CH2-CH2-O.
(Where . represents a free radical)

After termination of the reaction with alcohol,what is a possible formula of such a non-ionic reagent?
A. (CH3(CH2)10 O)10 CH2CH2OH
B. CH3(CH2)10 O (OCH2CH2)10 OH
