My question is that Single displacement reactions are reactions where one reactant replaces part of the other.
AB + C → AC + B//mechanism
Double displacement reactions are reactions where part of one reactant is replaced by part of another reactant.
AB + CD → AD + CB//mechanism
in inorganic chemistry.
by AB AND CD mechanism we can figure out AC +B is a product of single displacement reaction.
In these type of reactions we can write their products of their reactants.
but in organic chemsitry we cannot write products of the reactants like susbstituion,nucleophilic reaction.Iget confused.
Like in inroganic chemistry we have
AB + C → AC + B//mechanism so are there mechanism in organic chemistry by that twe can write products when reactants are reacting.
AB + C → AC + B//mechanism
Double displacement reactions are reactions where part of one reactant is replaced by part of another reactant.
AB + CD → AD + CB//mechanism
AB + C → AC + B//mechanism so are there mechanism in organic chemistry by that twe can write products when reactants are reacting.

How would you account for the following: (i) Phenols are much more acidic than alcohols. (ii) The boiling points of ethers are much lower than those of the alcohols of comparable molar masses.

On what basis does the R-O Cleavage takes place when R-O-R reacts with HI ?
eg-: CH3-CH2-CH2-O-CH3 + HI ---> CH3-CH2-CH2-OH + CH3I ,
Why is the product not CH3-CHI-CH3 + CH4 ?
eg-: CH3-CH2-CH2-O-CH3 + HI ---> CH3-CH2-CH2-OH + CH3I ,
Why is the product not CH3-CHI-CH3 + CH4 ?
