Which of the following compounds is not chiral?
1-chloro-2-methyl pentane
2-chloropentane
1-chloropentane
3-chloro-2-methyl pentane
Which of the following is a nucleophile?
BH3
NH3
AlCl3
All of these
B.
NH3
Nucleophiles (i.e., nucleus loving) are the species that have atleast one lone pair of electrons for donation. Therefore, they are also known as Lewis bases.
Among all the given options, BH3 and AlCl3, being electron deficient, behave like electrophiles while H3, due to the presence of a lone pair over N, is a nucleophile.
The IUPAC name of the following compound is
3-ethyl-2-methylbutanal
2, 3-dimethylpentanal
2-ethyl-3-methylbutanal
2-ethyl-3-methylbutan-3-al
Which of the following is not a isomer of pentane?
n-pentane
2, 2-dimethyl 1-propane
