Nice

[@galaxygaming6280]

Sir can you explain how to calculate theoretical yield?

[@_cyrab]

Hello, how long does it really takes for the entire experiment? And each stage reflux, crystallisation and recrystallisation?

[@DrGSR]

One to one and half hour

[@sayedpacha1253]

Hello what is the yeild produced

[@DrGSR]

Yeild = experimental mass of phenol benzoate/ theoretical mass of phenol benzoate. *100
= experimental mass/2.254. *100
[1ml of phenol theoretically gives 2.254g of phenol benzoate.].

Sir what is the melting ponit

[@DrGSR]

You mean MP definition or MP of that compound.

[@DrGSR]

69degŕee Celsius is pure phenyl benzoate mp.

Benzoyl chloride ka derivative kia hota?

[@DrGSR]

It is good acylating agent (electrophile) it react with alcohols gives esters and many derivatives can be produced

[@mehwishfatima4746]

@@DrGSR plz tell me derivative of benzyol chloride

[@DrGSR]

@@mehwishfatima4746 benzophenone is one of the derivative of benzoyl chloride, when it reacts with benzene in presence of AlCl3

[@mehwishfatima4746]

@@DrGSR can you tell me what benzamide also derivative of benzyol chloride?

[@DrGSR]

@@mehwishfatima4746 yes, if you treat benzoyl chloride with Ammonia it gives benzamide
