a)CH3-CH2-CH2-CH3+O2---->
B)CH3-CH2-CH2-CH2-CH3+Br2---->
c)CH3-CH=CH-CH3+Br3---->
D) HEXENE+KMnO4-->
E) HEXENE+Br2---->

a) To predict the products of a reaction, we need to consider the types of reactants involved and the general reactions they undergo. In this case, CH3-CH2-CH2-CH3 (butane) reacts with O2 (oxygen). Since butane is an alkane and oxygen is a highly reactive gas, we can predict that the reaction will undergo combustion.

The general combustion reaction of an alkane with oxygen is as follows:
alkane + oxygen --> carbon dioxide + water

Applying this reaction to butane, we can predict the products to be carbon dioxide (CO2) and water (H2O):
CH3-CH2-CH2-CH3 + O2 --> CO2 + H2O

b) CH3-CH2-CH2-CH2-CH3 (pentane) reacts with Br2 (bromine). Bromine is a halogen and reacts with alkanes to replace a hydrogen atom, resulting in the formation of an alkyl halide.

The reaction between pentane and bromine is an example of a substitution reaction:
alkane + halogen --> alkyl halide

Applying this reaction to pentane and bromine, we can predict the products to be pentyl bromide:
CH3-CH2-CH2-CH2-CH3 + Br2 --> CH3-CH2-CH2-CH2-CH2-Br

c) CH3-CH=CH-CH3 (butene) reacts with Br3 (bromine). Bromine reacts with alkenes in an addition reaction where the bromine molecule adds across the double bond.

The reaction between butene and bromine is an example of an addition reaction:
alkene + halogen --> dihalide

Applying this reaction to butene and bromine, we can predict the product to be 1,2,3,4-tetrabromobutane:
CH3-CH=CH-CH3 + Br3 --> CH2Br-CHBr-CHBr-CH2Br

d) HEXENE (a generic term for a hexene isomer) reacts with KMnO4 (potassium permanganate). Potassium permanganate is a strong oxidizing agent and, in the presence of an alkene, undergoes a reaction called oxidative cleavage.

The reaction between hexene and potassium permanganate results in the formation of two carboxylic acids:
alkene + oxidizing agent --> carboxylic acid + carboxylic acid

Since "HEXENE" can refer to multiple isomers, it is difficult to predict the specific products without knowing the exact structure of the hexene isomer.

e) HEXENE (a generic term for a hexene isomer) reacts with Br2 (bromine). Bromine reacts with alkenes in an addition reaction where the bromine molecule adds across the double bond.

The reaction between hexene and bromine is an example of an addition reaction:
alkene + halogen --> dihalide

Since "HEXENE" can refer to multiple isomers, it is difficult to predict the specific product without knowing the exact structure of the hexene isomer.
