Which of the following is not the product of a radical chain-reaction of 2-pentene with NBS?
Question 2Dipole moments of CH3X are 1.85, 1.87, 1.81, and 1.62 D for F, Cl, Br, and I, respectively. What is the best explanation of the small differences in dipole moments?
1.The electronegativity of halogens in alkyl halides is nearly constant.
2.The inductive effects are counterbalanced by hyperconjugation.
3.The electronegativity effects are counterbalanced by bond strengths.
4.Lone-electron pairs are more delocalized on smaller halogens.
5.The charge-separation and bond-lengths trends have opposite effects.
For this bimolecular reaction, the rate constant k is second order
