Oxidation of alcohol:
Alcohols reacts with hypochlorous (oxidizing agent) in the presence of acetic acid which yields the corresponding
Primary alcohols gives aldehyde, secondary alcohols gives ketone.
The alcohols reacts with acids like hydrochloric acid or hydrobromic acid, the bromine atom attacks back side of the carbon atoms which is bearing alcohol group and yields the corresponding product.

- e. If (3R,4R)-3,4-dichloro-2,5-dimethylhexane and (3R,4S)-3,4-dichloro-2,5-dimethylhexane are in a solution at the same concentration, would this solution be expected to rotate plane polarized light (that is, be optically active)? Please provide your reasoning for your answer. [If you read this problem carefully, you will not need to draw out the structures to arrive at your answer...]arrow_forward1. How many neighbors does the proton that produces the multiplet below have? 2. 3. اللـ Draw a partial structure from the multiplet below. (The integration of the multiplet is 6) M Using the additivity constants found in appendix G of your lab manual, calculate the approximate chemical shifts of the protons indicated below. (Show your work!!!) B A Br SHarrow_forward1) Suppose 0.1 kg ice at 0°C (273K) is in 0.5kg water at 20°C (293K). What is the change in entropy of the ice as it melts at 0°? To produce the original "water gas" mixture, carbon (in a combustible form known as coke) is reacted with steam: 131.4 kJ + H20(g) + C(s) → CO(g) + H2(g) From this information and the equations in the previous problem, calculate the enthalpy for the combustion or carbon to form carbon dioxide. kindly show me how to solve this long problem.

Composite materials can only be: metal-polymer or polymer-polymer.(B). Composite materials can be made up of particles, but not fibers or sheets.(C). When the reinforcing particles are uniformly distributed in a composite material, there may be a greater tendency for it to have isotropic properties.(D). None of the above is correct.arrow_forwardIf we are talking about viscoelastic modulus or viscoelastic relaxation modulus in polymers, indicate the correct option.(A). It reports the variation of elastic behavior as a function of time.(B). It is only useful for defining its glass transition temperature.(C). It only allows us to define the polymer degradation temperature.(D). Neither option is correct.arrow_forward
