E] Nomenclature of carbon compounds containing functional groups
(halogens, alcohol, ketones, aldehydes, esters)
i)Definition & Types of Functional groups.
1. What is a functional group?

2. Give the chemical structures of the functional groups present in- a. halogens,
b. alcohol, c. ketones, d. aldehydes, e. esters, f. Carboxylic acid group.
Carboxylic acids- [-COOH]
3. Name the structure given below. Identify the functional group. Draw the Lewis
structure of the second member of that homologous series.
CH – CH – CH - CH – CH – CH OH
3 2 2 2 3

4. a) Which part of an organic compound decides its physical property and
which decides its chemical properties?
b) Write the formulae of the predecessor and successor of the following:
(i) C 2H 5CHO (ii) CH 3COOH

F] Chemical properties of carbon compounds (combustion, oxidation, addition
and substitution reaction). Ethanol and Ethanoic acid (only properties and
uses),

1. An organic compound burns with a sooty flame. Is it a saturated or an
unsaturated hydrocarbon? Give reason.

2. Hydrocarbon `X` and `Y` are having molecular formulae C3H8 and C3H6
respectively. Both are burnt in different spatula on the Bunsen flame. Indicate
the colour of the flame produced by `X` and `Y`. Identify `X` and `Y`. Write the
structural formulae.

3. Name the product other than water formed on burning of ethanol in air. What
is the colour of flame obtained during this combustion process. Give the
balanced chemical equation for the reaction taking place.

4. Name the products formed when ethanol burns in air. List two forms of energy
that are liberated on burning ethanol.

5. Do the following conversions –
1. Ethene to Ethane
