Draw the product of the reaction ch3ch2ch2ch2c? cch3+2br2? ?

I will assume that the sign ? between the C and the CCH3 is a triple bond, and I will represent it by three vertical lines |||

So the reaction is:

CH3CH2CH2CH2C ||| CCH3+2Br2 >

This is a typical reaction known as halogenation of alkines.

This is an addition reaction, i.e. the alkyne undergoes an addition of the Br2 (and it also happens with Cl2) to the triple bond to form a tetra halide.
