Concept explainers
(a)
Interpretation:
The given set of compounds has to be arranged in the increasing order of boing point.
Concept introduction:
The boiling points of carboxylic acids are higher than those of alcohol or
Intermolecular hydrogen bonding will increase the boiling point of an organic compound.
Carboxylic acids can form dimers in which hydrogen bonds form between two carboxyl groups this will also increase their boiling point.
Increasing order of boiling point of some organic compounds with similar molecular weight is shown below,
The better hydrogen bond capability of a molecule will increase its boiling points.
(b)
Interpretation:
The given set of compounds has to be arranged in the increasing order of boing point.
Concept introduction:
The boiling points of carboxylic acids are higher than those of alcohol or aldehydes of similar relative molecular mass due to intermolecular hydrogen bonding.
Carboxylic acids can form dimers in which hydrogen bonds form between two carboxyl groups this will also increase their boiling point.
Intermolecular hydrogen bonding will increase the boiling point of an organic compound.
Increasing order of boiling point of some organic compounds with similar molecular weight is shown below,

- Methyl isocyanate, CH3 -N= C = O, is used in the industrial synthesis of a type of pesticide and herbicide known as a carbamate. As a historical note, an industrial accident in Bhopal, India, in 1984 resulted in leakage of an unknown quantity of this chemical into the air. An estimated 200,000 people were exposed to its vapors, and over 2000 of these people died. Q.) Methyl isocyanate reacts with strong acids, such as sulfuric acid, to form a cation. Will this molecule undergo protonation more readily on its oxygen or nitrogen atom? In considering contributing structures to each hybrid, do not consider structures in which more than one atom has an incomplete octetarrow_forwardName the following using IUPAC system of nomenclature: (a) CH2 (Cl) CH (NH2) CHO (b) CH3 C (Br) CH2 CH (F) COOH Brarrow_forwardGive a common name (when possible) and a systematic name for each compound. ) (h) CH3C‚CCH2OCH3arrow_forward

Draw skeletal formulae to show the structure of the two stereoisomers of but-2-enal. (b) (i) Describe a simple chemical test that would show that but-2-enal is an aldehyde. (ii) Explain why this test gives a different result with aldehydes than it does with keton (c) But-2-enal also reacts with sodium borohydride, NaBH4. (i) Identify the organic compound formed in this reaction. (ii) State the type of chemical reaction occurring. (d) Precautions must be taken to prevent but-2-enal catching fire.
