Answer: C4H
Explanation:
An hydrocarbon is a compound with carbon and hydrogen atoms only covalently linked together.
Thus, all hydrocarbons have a basic formula of CH.
Now, mass of hydrocarbon = 100%
Mass of hydrogen = 20%
Mass of carbon = (100% - 20%) = 80%
i.e Carbon : Hydrogen
= 80% : 20%
= (80% / 20%)
= 4 : 1
Thus, the empirical formula of the hydrocarbon is C4H
Answer: NH3 and NH3
Explanation:
If hydrogen is bonded to a highly electronegative element, a strong dipole-dipole attraction is set up with strength ten times greater than normal dipole-dipole attractions, and it is crystal clear that electronegativity increase from left to right across the period and it decreases down the group. Nitrogen being electronegative more than Oxygen will exhibit a greater dipole-dipole attraction. As such, NH3 and NH3 is the right answer.
