Tricks to decide Hybridization

There are a number of tricks to decide the hybridization state of an atom in a molecule or polyatomic ion. Some of the most common tricks to decide hybridization state are discussed here-

(1) Hybridization in an atom of second period =  spn-1

Where, n = No. of bonds made by the atom + no. of lone pairs on the atom

                   = No. of atoms bonded to the atom + no. of lone pairs on the atom

Fact- Lone pair of electrons usually occupy hybridized orbitals.

For example, in the following compound-

                          CH3 CH2 ─ C≡N:

Hybridization in nitrogen atom =  spn-1

          Here, n = no. of  bonds made by the atom + no. of lone pairs on the atom

                       = 1 (triple bond) + 1 (Lone pair)                        

                       = 2

 Hybridization in nitrogen atom =  sp2-1

                                                    =   sp

Hybridization in carbon atom of CN group =  spn-1

          Here, n = no. of bonds made by the atom + no. of lone pairs on the atom

                       = 1 (triple bond) + 1 (single bond) + 0 (Lone pair)

                       = 2

Hybridization in carbon atom of CN group =  sp2-1

                                                                     =   sp

Important Tips for Preparation of NEET/IIT-JEE

(1) Select a good mentor of Chemistry. Several educational channels and the best mentors of Chemistry are available on YouTube for free. You may follow one of them rather than wandering here and there.

(2) Centralize your study to the NCERT books and one or two reference books of organic Chemistry. Don’t follow too many books otherwise, you would not be able to complete your syllabus. Always remember, different books differ being only nineteen or twenty in text quality, but never differ of being nineteen and twenty-five. 

(3) Follow quality notes of a good mentor. Don’t run behind the brand, but run behind the concise and effective notes of your mentor.

(4) Prepare your own capsule notes for revision.

(5) Maintain consistency and regularity in your preparation.

(6) Revise the prepared topics regularly. Always remember, revision is not a waste of time but it makes you perfect. Always keep in mind that, “Revision is division” i.e. Revision improves your marks and ultimately your rank in the final selection.

(7) Solve practice problems and previous year’s papers in the specified time frame. It would help you to finish your paper timely in the final examination.

(8) Always be confident in your preparation, but never be overconfident. Always read the question carefully and then answer. You usually make mistakes in overconfidence and it has to be reduced.
