Q2-Σ Notation Review notation by investigating In this problem we will remind ourselves of 2k k O a) Consider the similar finite sum 2* k-0 Using n - 3, rewrite this expression in expanded form, and then evaluate it. b) Rewrite Expression (2) in expanded form for n-6, and then evaluate it c) Expression (2) becomes a better approximation to Expression (1) as n grows larger. To get an idea of what (1) is, evaluate (2) using n 100. Don't...

1. Draw an energy diagram showing the conformational analysis of
the following compound, viewed along the C2-C3 bond. Clearly
identify relative stability of staggered conformations as well as
eclipsed conformations, taking into account gauche interactions and
hydrogen-bonding interactions. Justify your choices through
explicit reference to interactions occurring in various
conformations.

1. How many different ways can you have r numbers 1 sum up to a number n? These are called compositions of a number n and it is easy to calculate from our understanding of binomial coefficients. So the number of compositions of 4 into 3 parts will be 1+1+2, 1+2+1, and 2+1+1. Note how we think of 1+1+2 and 1+2+1 as different-because in the first case, the first number is 1, second is 1 and third is 2, while...

1.The best way to describe the "arrow" showing the mechanism of EAS is: A.it goes from the attacking atom (electrophile) to the carbon being attacked. B.it goes from the attacking atom to the new bond being formed. C.it goes from the electron pair in the pi-bond on the ring to the new sigma bond being formed. D.it involves a half-head arrow from the attacking species and a half-head arrow from the pibond to the new sigma bond to be formed....
