Chlorohexane which is also known as hexyl chloride is a halogened hydrocarbon which can be produced by treating 1-heaxnol with fuming HCl or with excess SOCl2 or with PCl5 and ZnCl2.
Which of the alkyl chlorides undergoes dehydrohalogenation in the presence of a strong base to give pent-2-ene as the only alkene product - the choices are: A 2-chloropentane B 1-chloro-2-methylbutane C 1-chloropentane D 3-chloropentane The answer is: 3-chloropentane
Propanol (D) is the most soluble in water among the given options. It can form hydrogen bonds with water molecules due to its hydroxyl group, enhancing its solubility in water. The other compounds lack significant functional groups to facilitate bonding with water molecules.
H₂C=CH₂ or C2H4. This molecule is called "Ethylene" and is a hydrocarbon with a double bond between the carbon atoms.
1. Explain with suitable examples: a) Both chlorobenzene and chloroethene do not undergo substitution reactions under ordinary conditions with NaOH. b) Carbonyl group of benzaldehyde is less reactive towards nucleophilic addition reactions than the carbonyl group of ethanal. 2. Write the product (s) and mechanism for the following reactions: (5) 3. How would you carry out following conversions? a) Ethene to oxirane b) Benzyl magnesium chloride to 3-phenylpropanol c) Propene to glycerol d) Benzaldehyde to 3-phenylpropenoic acid e) Ethanol to trichloromethane (5) 4. a) How would you differentiate between different classes of alcohols? b) Give two reduction methods which can convert a carbonyl compound to an alkane.

The carbon skeleton of pentane contains 5 carbon atoms, the carbon skeleton of heptane contains 7 carbon atoms. The main reason for increased boiling point are London dispersion forces, these increase the with the number of electrons- so as heptane has more electrons its dispersion forces are greater and the boiling point is higher. Another contributory factor is the mass as the molecule of heptane is heavier and this means it takes more energy to get it to vaporise.
