How can you prepare para-nitro acetanilide from acetanilide?
used of para nitro acet anilide
Why in bromination of acetanilide using bromine in acetic acid give para bromoacetanilide as major product?
The -NHCOR group is less powerfully activating then the -NH2 group. In addition, the degree of steric hindrance is much greater in the case of a -NHCOR group, such as is found in acetanilide. This results in the compound being much more para directing. For an example, see Morrison and Boyd 's text "Organic Chemistry", sixth edition, Page 848.
Why acetanilide brominates in the ortho and para positions and the amount of o-bromoacetanilide?
The polarization of bromine in bromoacetanilide reaction
What is the function of acetic acid in the preparation of para nitro acetanilide?
it holds the carbocation that is formed in "soultion" so it is able to react to completion
What is the melting point of Kevlar?
Kevlar does not have a melting point, as its polymers disintegrate before they could ever reach such a point.

How can seprate p-nitro acetanilide mixture of para and ortho acetanilide?
The amide group on acetanilide is an ortho/para director, so a simple nitration should work: a mixture of sulfiric acid and nitric acid should be sufficient. Afterward, separation of the ortho and para compounds (by column chromatography, probably) would be necessary.

Why para-nitro acetanilide is insoluble in water whereas ortho-nitro acetanilide is soluble in water?
p-nitro phenol has a symmetric structure as compare to o-nitro phenol so it has higher dipole moment or polarity so is more soluble.
Why is only 4-bromoacetanilide created mainly from a bromination of acetanilide?
The Acetanilide is a benzene with a acetamido group attached to it. The acetamido group is electron donating and therefore it directs other substituents to the ortho and para positions. The acetamido group is also a very large group and the ortho position is right besides the acetamido group. This creates steric hindrance from bromine from getting to the ortho position and therefore only para-bromoacetanilide or 4-bromoacetanilide is created mainly from a bromination of acetanilide.
Why does para-chlorophenol melts at 43 degrees Celsius and ortho-chlorophenol melts at 9 degrees Celsius?
34
Why is the melting point of 4-bromonitrobenzene much higher than the melting point of 2-bromonitrobenzene?
At first glance one might think that since 2-nitophenol (ortho) is more polar than the para form that it would have the higher melting point, but if you check the related link you will find a discussion of why you must "look at both enthalpy AND entropy trends to do a good job of comparing melting (and boiling) points for related compounds".
