Both are mainly composed of droplets of condensed water
To get the molecular formula we use the individual atomic masses of the atoms making the molecule. Hence, to get the factor by which the empirical formula is multiplied, we divide molar mass by the total of the mass of the atoms making the empirical formula.
(C2H7) the mass of one carbon atoms is 12 so two atoms add up to 24. The mass of one hydrogen atom is 1 a.m.u thus 7 atoms give a total of 7 a.m.u. The sum of the two types of atoms is 24+7= 31
Molar mass=62.18
62.18/31=2.0
Hence, (C2H7) 2=C4H14
Explanation:
A molecule with a triple bond will have a linear geometry as the angles between the bonds will be 180 degrees. Hence, it will be a linear geometry.
For example, a molecule of dinitrogen (
) has nitrogen atoms bonded through triple bond as follows.
:N ≡ N:
Since valency of nitrogen is 5 therefore, each nitrogen will have one lone pair of electrons.
