The answer is b physical change
Answer:
See explanation and image attached
Explanation:
The reaction of (R)-2-chloro-3-methylbutane with potassium tert-butoxide yields a monosubstituted alkene .
Since the base is bulky, the Hoffman product predominates because attack occurs at the less hindered carbon atom to yield the major product as shown.
The alkene reacts with HBr at the secondary carbon atom to yield a carbocation intermediate which is flat and planar. Attack on either face of the carbocation yields a racemic mixture of the (2R) and (2S) products.
Rearrangement of the carbocation to yield a tertiary carbocation gives the 2-bromo-2-methyl butane product as shown in the image attached.
Answer:
Nucleic acids
Explanation:
all organic foods (fruit, meat, etc) contain it to some degree. because all organic foods have dna in them.
°C = (°F - 32)/1.8
°C = (-143-32)/1.8
°C = -97.22
hope this helps :) (please mark brainliest if correct!)
