Introduction to Aldehydes and Ketones

The carbonyl functional group showing metamerism is

What is the hybridisation of the carboxyl carbon atom of carboxylic acids?

Identify a ketone molecule, among the given compounds.

Identify a compound not having the carbonyl group.

The carbon-oxygen double bond in a carbonyl group is polar due to 

Aldehydes can be represented by the general formula

Which isomerism is shown by pentanone?

Write the IUPAC name of the following compound

Which of the following is a tricarboxylic acid?

Consider the following compounds



The correct decreasing order of their reactivity towards hydrolysis is

is the final product obtained when one of the following is reacted with base.

An aromatic compound $\mathrm{T}\left({\mathrm{C}}_{10}{\mathrm{H}}_{10}{\mathrm{O}}_2\right)$ give 2 moles of ${\mathrm{CHI}}_3$ and compound $\mathrm{U}\mathrm{ }\left({\mathrm{C}}_8{\mathrm{H}}_4{\mathrm{O}}_4{\mathrm{Na}}_2\right)$ On treatment with ${\mathrm{I}}_2$ and $\mathrm{NaOH}$ . After acidification U gives two mononitro products on nitration.

Compound (T) can also be obtained by ozonolysis of V,in this ozonolysis one mole of $\mathrm{OHC}\mathrm{ }–\mathrm{ }\mathrm{CHO}$ is obtained along with (T). Choose the incorrect statement.

$C{H}_{3}CHO$

$\left(A\right) \mathrm{a}\mathrm{n}\mathrm{d} \left(C\right)$ are related as:

An organic compound $P\left(C_5{H}_{10}{O}_2\right)$ reacts with $B{r}_2$ in presence of phosphorus to produce Q which can be resolved into enantiomers. Q on dehydrobromination yields $R\left(C_5{H}_8{O}_2\right)$ which does not show stereoisomerism. R on decarboxylation gives an alkene which on further ozonolysis gives S and T. S gives Schiff's test but T does not. The correct identity of these compounds are

IUPAC name of ${\text{CCl}}_3\text{CHO}$ is

Ethanedial has which functional group(s)?

Which of the following statements is true about propanone with respect to $\mathrm{\sigma }-$bonds,$\mathrm{\pi }-$bonds and lone pairs of electrons, respectively?

In $\mathrm{H}\mathrm{C}\mathrm{H}\mathrm{O}$ , there are $\mathrm{X}$ non-bonding electron pairs, $\mathrm{Y}\mathrm{ }\mathrm{\sigma }-\mathrm{b}\mathrm{o}\mathrm{n}\mathrm{d}\mathrm{s}$ and $\mathrm{ }\mathrm{Z}\mathrm{ }\mathrm{\pi }-\mathrm{b}\mathrm{o}\mathrm{n}\mathrm{d}\mathrm{s},$ $\mathrm{X},\mathrm{ }\mathrm{Y}$ and $\mathrm{Z}$ are -
