It is neither a Lewis acid nor a Lewis base. In all the hydrides belonging to this type, the carbon atoms have complete octet. Therefore, these hydrides behave as normal covalent hydrides also called saturated hydrocarbons or alkanes, `(e.g., CH_(4),C_(2)H_(6),C_(3)H_(8)etc)`. These are also called electron precise hydrides. We shall study in details about these hydrides at a later stage in unit 13.
