1.Not all chiral molecules are required to have an individual atom that is chiral. For example, the allene below is chiral and optically active without a chiral carbon. Explain how this is the case and be sure to use a drawing to support your logic. HINT: Think about the orbitals and implication of their orientation. (5 points) Write your answer on a blank piece of paper to give us space to see what you write when we grade. Answers squeezed into small spaces or un-readable will be given an instant zero from this point on. 2. Provide an acceptable IUPAC name for the following molecules. Spelling and formatting are graded. (5 points) 3. For each set of molecules, identify the best nucleophile. For part c, circle the most nucleophilic atom. (3 points)

you should just be yourself and not let any body tell you other wise.

explanation:

why?

because if they don't love you for your self then they don't deserve you.

when 25.0 ml of 0.700 mol/l naoh was mixed in a calorimeter with 25.0 ml of 0.700 mol/l hcl, both initially at 20.0 °c, the temperature increased to 22.1 °c. the heat capacity of the calorimeter is 279 j/°c.

the equation for the reaction is:

naoh + hcl → nacl + h₂o

moles of hcl = 0.0250 l hcl ×

0.700

mol hcl

1 l hcl = 0.0175 mol hcl

volume of solution = (25.0 + 25.0) ml = 50.0 ml

= (22.1 – 20.0) °c = 2.1 °c

the heats involved are
