(N/A) Carbon hydrides of the type $(C_nH_{2n+2})$ are known as electron-precise hydrides.
They possess the exact number of electrons required to form the necessary covalent bonds in their structure.
Since they have no lone pairs to donate and no vacant orbitals to accept electrons,they do not exhibit any tendency to gain or lose electrons.
Therefore,they act neither as Lewis acids nor as Lewis bases.
