Is 4 Chlorobenzaldehyde a solid?

p-Chlorobenzaldehyde is a white solid with m.p. of 46~47 ℃, b.p. of 213~214 ℃ and n20D 1.5640, It is soluble in benzene, toluene and other solvents but insoluble in water.

Why boiling point of p hydroxybenzaldehyde is higher than salicylaldehyde?

Answer: To break these intermolecular H-bonds, a large amount of energy is needed. Consequently, p- hydroxybenzaldehyde has a much higher m.p. & b.p. than that of o- hydroxybenzaldehyde.

What is difference between biphenyl and diphenyl?

As nouns the difference between diphenyl and biphenyl is that diphenyl is (organic compound) an alternative name of biphenyl while biphenyl is (organic compound|uncountable) a colourless solid hydrocarbon, c12h10, consisting of two benzene rings linked together.

Why is biphenyl soluble in hexane?

Biphenyl was insoluble in water as water is highly polar whilst biphenyl is nonpolar. Biphenyl was partially soluble in methanol which is intermediately polar whilst biphenyl is nonpolar, allowing it to dissolve a little. Biphenyl was soluble in hexane because both biphenyl and hexane are nonpolar molecules.

What IMF is biphenyl?

Biphenyl molecules have dispersion forces as their most important IMF. Biphenyl will not dissolve in water because water has hydrogen bonding as its most important IMF. If water and biphenyl interact they will interact weakly. Water pulls on water with more force than water pulls on biphenyl.
