no, this explnn is wrng bcs high electronegativity diff leads to smaller bond lenght that's why, C-- N < c--="" c="" in="" bond="" lenght="" order..="" but="" c="N" /> C=C a/c to ncert.. ppss expln anyone

good question.Chemistry me kai baar aise cases aate hi jaha Theoretical Concepts aur Experimental Data contrary ho jaate hi. specially Inorganic Chemistry me jaha exceptions bahot sare hi.NCERT class 11th Page no. 103 pe 2nd last para, 3rd line pe ye bolti hi ki Bond Length are measured by Spectroscopy, X-Ray diffraction and electron- diffraction technique. i.e. Bond Length is a Practical Data, not a Theoretical data.wo to hm apni understanding ke liye rules bnate hi ki jb E.N difference hoti hi to Bond Length decrease ho jati hi, jis se uski Strength increase ho jati hi. ye concept maximum pe apply ho bhi jata hi. pr aap ise sabhi pe apply nahi kr sakte.NCERT 11th ne page no. 104, table 4.2 me Practical Data de rakha hi and ye statement usi data ke last ki 4 values me se hi.agr iska koi explanation hota, to NCERT khud hi deta, ya students ko findout krne ko proper mention krta, pr NCERT ne aisa nahi bola, because Practically obtain datas pe koi debate nahi hoti.ab agr aap iska theoretically kisi se bhi explanation mangoge to may be log apne apne ideas se link kare, pr exact answer aap nahi pa sakte.aap above question ko statement maan ke learn kr lo, koi bhi Exam me Practical Basis pe aise Question puch to sakta hi, pr explanation kabhi nahi mangega.
