What effect does branching of an alkane chain has on its boiling point ?
Branching of an alkane chain makes the molecules more compact and brings various atoms closer. As a result, the molecular size decreases. This decreases the surface area and therefore the magnitude of Vander Waal's forces also decreases. Hence the boiling point of the alkane decreases with branching.
In the alkane H3C - CH2 -C(CH3)2 -CH2 - CH(CH3)2, identify 1°, 2°, 3° carbon atoms and give the H atoms bounded to each one of these.
Write the structure of the given compound in expanded form.
15H attached to five 1° carbons
4H attached to two 2° carbons
1H attached to one 3° carbon
For the following compounds, write structural formulas and IUPAC names for all possible isomers having the number of double or triple bond as indicated:
Suggest the name of a Lewis acid other than anhydrous aluminium chloride which can be used during ethylation of benzene.
