So, I will make you understand whether HCN is polar or not and the reason behind that. This leads to a strong pull of the electron pair on both sides (because both the elements are highly electrophile), altering the otherwise straight bond. O polar Carbon dioxide(CO2) is one example of this type of phenomenon. The polarity of a covalent bond can be judged by determining the difference of the electronegativities of the two atoms involved in the covalent bond, as summarized in the following table: Electronegativity Difference. Accordingly, carbon and hydrogen share electrons of each other and forms a covalent bond(C-H) whereas carbon and nitrogen form a triple bond (CN) to share their three electrons with each other. Balance each of the following equations by writing the correct coefficient on the line.
