The smallest straight –chain alkane which is a liquid at room temperature has to be identified. Concept introduction: Boiling point of alkanes : The linear chain alkanes have a higher boiling point when compare to other branched-chain alkenes , it is due to the greater surface area in contact thus the greater van der Waals force between the adjacent molecules. Bond angle: The bond angle is the angle formed between three atoms at least two bonds. Polarity: It is a well separation of electric charge leading to a molecule or chemical compounds having an electrical dipole moment. Generally the polar molecules must contain polar bonds due to a different in electronegative between the bonded atoms.
