A) high M.R and high B.R
B) high M,R and low B.R
C) low M.R and high B.R
D) low M.R and low B.R
Correct Answer: A
Solution :
Ionic compounds have high melting and boiling points, because of the presence of strong forces of attraction between the ions in the crystal of an ionic compound. The ionic bond is very strong and hence a large amount of thermal energy (high temperature) is required to overcome these forces and break down the crystal lattice.)
