      • If you go down group 7, the electronegativity is lower. This reduces the polarity of the bond. Since the carbon atom in the bond is delta positive, it will attract nucleophiles. These nucleophiles will react with the halogen in substitution reactions and will replace the halogen forming a different functional group. (E.g. H2O, OH^-, NH3)

    • In carbon-halogen bond, halogens have significantly greater electronegativities than carbon except iodine. In result, this functional group is polarized so that the carbon is electrophilic and the halogen is nucleophilic. Halogenoalkanes are can be classified depending on the halogen atom position on the chain of carbon atoms.

Because CH 3 and CH 2 groups cannot be chiral centers, this molecule has only three carbons that could be chiral centers. The two leftmost possibilities, identified in the next figure, have four nonidentical groups and are chiral centers, but the one on the far right has two identical methyl (CH 3) groups and so is not a chiral center.

A good way to think of the reaction is that the pi bond of the alkene acts as a weak nucleophile and reacts with the electrophilic proton of HBr. Alternatively, you can view the first step of the reaction as the protonation of the pi bond.

C4H9Br is also known as butyl bromide. The four isomers of C4H9Br are four isomeric alkyl bromides. 1-bromobutane is also known as n-butyl bromide, 2-bromobutane is also known as sec-butyl bromide, 1-bromo-2-methylpropane is also known as isobutyl bromide, and 2-bromo-2-methylpropane is also known as t-butyl bromide.216 S11-E2 Page 2 Name _____Key_____ I.

Alkynes are organic molecules made of the functional group carbon-carbon triple bonds and are written in the empirical formula of (C_nH_{2n-2}). They are unsaturated hydrocarbons. Like alkenes have the suffix -ene, alkynes use the ending -yne; this suffix is used when there is only one alkyne in the molecule..
