In a sample of bonds in the position. (Note: Remember that iodine () is larger and more likely to contribute to steric strain in the molecule.) iodocyclohexane (CH), one would expect to find most of the C-I O equatorial O trigonal pyramidal O tetrahedral Oplanar O axial Question 7 The molecule aniline is pictured here. Which of the following words could be used to describe an essential feature of aniline to someone who is familiar with chemistry, but not with this molecule? O aromatic O heterocycle O non-cyclic fused-ring system O alkane NH₂
