The Alkene which on ozonolysis gives acetaldehyde and acetone is

P is an alcohol which on heating with \displaystyle{A}{l}_{{{2}}}{O}_{{{3}}}_{\left({3}\right)} forms an alkene Q. Q on ozonolysis produces R and S. when the mixture of R and S is heated with conc. $NaOH$, redox reaction takes place and a mixture of an acid salt and alcohol is formed.
The compound (Q) is

Aldehyde and ketone undergo nucleophilic addition reaction because of polarity between $>C=O$ group . The reactivity of carbonyl groups toward nucleophile depends upon the nature of inductive effect of froup present at carbonyl carbon.
Which among the following is more reactive towards nucleophilic addition reaction

Aldehyde and ketone undergo nucleophilic addition reaction because of polarity between $>C=O$ group . The reactivity of carbonyl groups toward nucleophile depends upon the nature of inductive effect of froup present at carbonyl carbon.
Nucleophilic addition reaction over carbonyl compound is shown by :
