Answer #1

A) C5H12 has higher melting point than KF because KF is ionic bonding and C5H12 is a solid held together by covalent bonds.So for melting covalent bonds are stronger than ionic bond.So KF has less melting than C5H12

B) KF is crystalline solid C5H12 is not crystalline solid

C) amphorous solids do not possess regularly order arrangement

C5H12 is amphorous solid

D) volatile means it easily vapourize, pentane (C5H12 ) is high volatile compound

F) polar molecules are easily soluble in water .KF is polar so it high solubility in water. Pentane is non polar molecule so it has less solubility.

G) first of all.All organic compounds are dissolve in oil.so pentane (C5H12 ) is organic compound so it dissolve in oil.KF is dissolve less than pentane
