Name reaction is a chemical
reaction which is named after the person who developed or discovered it. For
class 12 students and medical/engineering aspirants, these Organic Chemistry
Name Reactions are very crucial as these are frequently asked in Class 12th
Board exam and competitive exams like NEET, JIPMER, JEE Main and JEE Advanced.
As, syllabus of Class 11th and Class 12th Chemistry is so wide, a selective and
smart learning in Organic Chemistry plays an important role to score well with
efficiency. Thus, we are providing here the 30 most important name reactions in
Organic Chemistry that every aspirant must know. These are prepared by Subject
Experts at MTG after analyzing previous years’ papers of various competitive
exams.
But, before we go further, we
would like to add- don’t
try to rote learn Organic Chemistry, you’ll fail, miserably. It’s good if
you clear your basic concepts first. And to grasp the basic concepts, refer to
the NCERT books and develop better understanding by
practicing from NCERT at your
Fingertips . The combination of both will lend a crystal-clear
understanding of each and every NCERT concept. You can also refer to Interactive Organic Chemistry book. It is
designed to provide a blend of theoretical clarity on all the topic of Organic
Chemistry along with optimum number of solved examples, flow charts and
practice exercises.
Now coming to the
top 10 Important Name Reactions which every NEET and JEE aspirants should know,
here we go:
1. Aldol condensation
Two
molecules of aldehydes or ketones having a-hydrogen condense together in
presence of base [dil. NaOH, Na2CO3, Ba(OH)2]
to form b-hydroxyaldehyde or b-hydroxyketone respectively which are
collectively known as aldol.
2. Clemmensen reduction
In this method,
aldehydes and ketones are reduced with Zn – Hg amalgam and conc. HCl.
3. Crossed aldol condensation
Aldol condensation
of different molecules of aldehydes or ketones or one of aldehyde and one of
ketone is known as crossed aldol condensation. Crossed aldol condensation
yields a mixture of different products.
4. Cannizzaro reaction
It
is a self-oxidation-reduction reaction in which aldehydes that do not have any
a-hydrogen atom undergo disproportionation reaction (i.e., self-redox
reaction) in the presence of 50% aqueous or ethanolic solution of alkali in
which one of the molecule being reduced to alcohol and other being oxidised to
the salt of corresponding acid.
5. Etard reaction
Aromatic
hydrocarbons on treatment with mild oxidizing agents such as chromyl chloride
CrO2Cl2 yield aldehydes.
These are some of the most
important reactions of Chemistry which were asked frequently in NEET, AIIMS,
JIPMER, JEE Exams and CBSE Class 12 Chemistry board exam. Students preparing
for such exams this year in 2020 must learn these important name reactions in
Organic Chemistry.
