2- Uscharidin is the common name of a poisonous natural product having the structure shown. Write and Express its functional group names for Uscharidin. (Alcohol, olefin, ether aldehyde, ketone, and ester, so on.) 3. For the substitution reactions below, why are different temperatures needed and they have different reaction rate? Explain in a few sentences. Tertiary alcobols are canvened to alkyl chlorides in Myh yicld within minutes ce reaction with hydrogen chloride at foom inmperaturt and briow.

Write and Express its functional group names for Uscharidin. (Alcohol, olefin, ether aldehyde, ketone, and ester, so on.) 3- For the substitution reactions below, why are different temperatures needed and they have different reaction rate? Explain in a few sentences. Tertiary alcohols are converted to alkyl chlorides in high yield within minutes on reaction with hydrogen chloride at room temperature and below. Secondary and primary alcohols do not react with hydrogen chloride at rates fast enough to make the preparation of the corresponding alkyl chlorides a method of practical value. Therefore, the more reactive hydrogen halide HBr is used; even then, elevated temperatures are required in order to increase the rate of reaction. 4- For the reactions below, what is the name of each step? Overall Reaction: (CH3)3COH+HC(CH3)3CCO+HOHtersAlafyl Step I: Photonation of tert-buryl alcohol to give an exonium inne Step 2: Diswociation of terthutylosonium in te give a carbocation: Step 3: Captare of Nert-buty cation by claloride ion
