Determine number of the sigma (sigma) and pi (pi) bonds in acrylonitrile: 6 sigm

Question

Determine number of the sigma (sigma) and pi (pi) bonds in acrylonitrile: 6 sigma, 2 pi 9 sigma, 3 pi 6 sigma, 5 pi 2 sigma, 6 pi 6 sigma, 3 pi Which one of the following molecules is polar? CH_4 CHBr_3 F_2 CBr_4 CO_2 A polar covalent bond would form between which one of these pairs of atoms? Cl and Cl Si and Si Ca and Cl Cr and Br P and Cl Transition metals, like copper, are found in many types of biological molecules where it is common for metals have deviations from ideal bond angles. Plastocyanin, a protein involved in electron transfer, contains a copper atom bonded to nitrogen or sulfur atoms found in amino acids. The bond angles range between 100 degree 108 degree. What type of geometry best describes the sulfur center affected by the copper atom in plastocyanin? square planar octahedral square pyramidal seesaw tetrahedral

Explanation / Answer

17) option B   CHBr3 is polar molecule

18) option E   P and Cl
