Why is the staggered conformation of ethane considered more stable than the eclipsed conformation?
The summary section states, 'Out of staggered and the eclipsed conformations of ethane, staggered conformation is more stable as hydrogen atoms are farthest apart.'
Which of the following describes a vinylic halide?
According to NCERT, vinylic halides are compounds in which the halogen atom is bonded to an $sp^2$-hybridised carbon atom of a carbon-carbon double bond (C=C).
In the IUPAC system, how are alkyl halides named?
The NCERT states: 'In the IUPAC system of nomenclature, alkyl halides are named as halosubstituted hydrocarbons.'
What is the classification of a compound where the halogen atom is bonded to an $sp^3$-hybridised carbon atom that is adjacent to a carbon-carbon double bond?
As per the NCERT text, 'Allylic halides: These are the compounds in which the halogen atom is bonded to an $sp^3$-hybridised carbon atom adjacent to carbon-carbon double bond (C=C) i.e. to an allylic carbon.'
For dihalogen derivatives of benzene, what prefixes are typically used in the common system of nomenclature?
The NCERT states: 'For dihalogen derivatives, the prefixes o-, m-, p- are used in common system but in IUPAC system, as you have learnt in Class XI, the numerals 1,2; 1,3 and 1,4 are used.'
Which of the following statements is true regarding haloalkanes and haloarenes?
According to the NCERT text, 'Haloalkanes contain halogen atom(s) attached to the $sp^3$ hybridised carbon atom of an alkyl group whereas haloarenes contain halogen atom(s) attached to $sp^2$ hybridised carbon atom(s) of an aryl group.'
What is the common name for $CH_2=CHCl$?
Table 6.1 in the NCERT lists 'Vinyl chloride' as the common name for $CH_2=CHCl$, with 'Chloroethene' being its IUPAC name.
If both halogen atoms in a dihaloalkane are present on adjacent carbon atoms, how are they classified?
The NCERT specifies: 'vicinal halides or vic-dihalides when halogen atoms are present on adjacent carbon atoms.'
What is the IUPAC name for 'sec-Butyl chloride'?
Referring to Table 6.1, the common name 'sec-Butyl chloride' corresponds to the IUPAC name '2-Chlorobutane'.
An alkyl halide where the halogen is attached to a carbon atom bonded to two other carbon atoms is classified as:
The NCERT states: 'if halogen is attached to secondary ... carbon atom, the alkyl halide is called secondary alkyl halide (2°)'. A secondary carbon atom is bonded to two other carbon atoms.
