WitrynaIn the original sequence: n=1 result=1 n=2 result=1+4 n=3 result=1+4+7 and so on. And if you look closely, each n is equal to the sum of an AP with r=3: The generic formula: Sum An = (A1+An)n/2 = (1+ (1+r (n-1))n/2 = (2+3n-3)n/2 = (3n-1)n/2.

WitrynaVideo transcript. Here's the general reaction for a hydrohalogenation. You have an alkene, and you react that with a hydrogen halide. And the hydrogen adds to one set of your double bond, and the halogen adds to the other set of your double bond. Let's look at the mechanism for this reaction. WitrynaFor cyclopentane, this bond angle is 108 degrees, and 108 degrees is pretty close to 109.5 degrees, closer than it would be for cyclohexane; This bond angle is 120 degrees. And so the theory was, cyclopentane is the most stable out of the cycloalkanes, because this bond angle is closest to 109.5 degrees.
WitrynaThe designation is used for stereo-isomers. Carbon has four bonds arranged in a tetrahedron, and each position on the tetrahedron is the same as every other, so it is possible to have four groups bonded to a carbon in different arrangements. Let`s take an imaginary molecule CHFClBr. Let`s look at the some of the possible structures.I have …
