question 20 (1 point)
which type of organic reaction is shown below?
ch₂==ch₂ + hbr ---> ch₃--ch₂br
a) addition
b) condensation
c) elimination
d) polymerization
e) substitution

Explanation:

In an addition reaction, two or more molecules combine to form a larger molecule. Here, \(CH_2 = CH_2\) (an alkene with a double bond) reacts with \(HBr\). The double bond breaks, and \(H\) and \(Br\) are added to the two carbon atoms (forming \(CH_3 - CH_2Br\)). Condensation reactions involve the loss of a small molecule (like water). Elimination reactions form a double bond by losing atoms/groups. Polymerization forms large polymers from monomers. Substitution reactions replace an atom/group in a molecule.

Answer:

A. addition
