Bond length is defined as the distance between the nuclei of two covalently bonded atoms. Something to add about bond length Bond length for a given pair of atoms: triple bond < double bond < single bond Bond strength for a given pair of atoms: triple bond > double bond > single bond In general, shorter the bond length, larger the bond strength

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
