Key Idea Count number of $\sigma$ bonds and then find hybridisation as follows. If number of $\sigma$ bonds $=2$; hybridisation is $\mathrm{sp}$, If number of $\sigma$ bonds $=3$; hybridisation is $\mathrm{sp}^2$, If number of $\sigma$ bonds $=4 ;$ hybridisation is $\mathrm{sp}^3$. ![NEET 2009 Chemistry, Chemical Bonding and Molecular Structure — solution figure](https://prepforbharat.s3.ap-south-1.amazonaws.com/exam/616059730283de43c87e3e22/Chemistry/images/Chemical_Bonding_and_Molecular_Structure/66bcbe69ae81d148616b1915/solution_1__q_66bcbe69ae81d148616b1915__cdn-question-pool.getmarks.app__MKZ6TELvSsyziTtcF4TLjFBkqh5k4RTku8GFWtLP1A0.original.fullsiz__fa4141a8cb_final_ppt_sync.png) Double and triple bonds are not considered while finding hybridisation.
