What is the common name of the given compound?
o-Toluidine (ortho-toluidine) is an organic compound with the chemical formula CH3C6H4NH2. It is the most important of the three isomeric toluidines.
Acrylonitrile is the common name of:
Acrylonitrile is an organic compound with the formula CH2CHCN. It is a colorless volatile liquid, although commercial samples can be yellow due to impurities.
Ambident group among the following are:
Ambident groups are those which can attack from both sides. So option a is correct because cyanides is C-N and carbon forms bonds here. Isocyanides are N-C in which nitrogen contains lone pairs which initiates reaction and attaches from nitrogen side.
The IUPAC name of
THe IUPAC name of p-bromoaniline is 4-bromoaniline. Carbon attached with NH2 acts as first position and then numbering is done.
Reduction of alkanenitriles with sodium and alcohol or LiAlH4 is called:
The reaction is a Mendius reaction as because in this reaction the organic nitrile is reduced by nascent hydrogen(from sodium in ethanol) to a primary amine. (RCN+2H2=RCH2NH2).
where as LiAlH4 is a strong reducing agent and can be used as an abstract source of H neucophile.
is a tertiary amine with IUPAC name:
The IUPAC name of tertiary methyl amine is N,N-Dimethyl-methanamine.
The carbylamine reaction is given by compounds having:
Carbyl amine reaction is given by aliphatic and aromatic primary amines.
Alkyl cyanides are isomeric with:
An isocyanide (also called isonitrile or carbylamine) is an organic compound with the functional group -N≡C. It is the isomer of the related cyanide (-C≡N), hence the prefix is isocyano. The organic fragment is connected to the isocyanide group via the nitrogen atom, not via the carbon.
Hydrolysis of methyl cyanides with dil. mineral acids gives:
C6H5-NH-C6H5 is :
In the structure two phenyl groups are attached to the amino group, hence the name Diphenyl amine.
Identify the most basic compound from the following.
CH3 is a electron donating group and benzene is a electron withdrawing group so option A and B are easily eliminated. Among C and D the +I effect of CH3 dominates over the stearic hindrance factor so D is most basic.
Amines that have one of their three hydrogen atoms replaced by an alkyl or aromatic substituent are referred to as
Amines that have one of their three hydrogen atoms replaced by an alkyl or aromatic substituent are referred to as primary amines.
Write the IUPAC name of the given compound.
Pyridine is less basic than triethylamine because:
Basicity of amines is due to availability of an unshared pair (lone pair) of electrons on nitrogen. This lone pair of electrons is available for the formation of a new bond with a proton or Lewis acid. Pyridine is less basic than triethylamine because lone pair of nitrogen in pyridine is delocalised.
If two hydrogen atoms of ammonia are replaced by alkyl group then the amine is:
If two hydrogen of ammonia are replaced by alkyl group then it forms secondary amine.
The shape of trimethyl amine is:
Trimethylamine is a base, like ammonia. Also like ammonia, it has a trigonal pyramidal structure. The C-N-C bond angle is 110.9°, compared with 107.2° in NH3, presumably due to greater repulsions between the methyl groups.
Benzonitrile is the IUPAC name of the compound:
According to IUPAC nomenclature, alkyl cyanides are called alkane-nitriles and benzyl cyanides are called benzonitrile.
IUPAC name of NH2CH2CH2CH2COOH is :
NH2CH2CH2 CH2 COOH is 4-Aminobutanoic acid , here carboxy group gets preferred over amino group as a main chain.
In amines ,the hybridisation state of N is:
Hybridisation of N in amine is sp3 with nitrogen having a one pair and 3 bond pair. Remember that amine is RR’R”N where R, R’ and R” may be alkyl or hydrogen.
Methyl cyanide on hydrolysis gives:
