Capitolo 15, Problema 56c
Draw the structural formulas of the following compounds:
c. 2-Methoxy-2-methylpropane
Guida verificata passo dopo passo1
Identify the parent chain: The parent chain is 'propane,' which indicates a three-carbon alkane backbone (C3H8).
Locate the substituents: The name '2-methoxy-2-methylpropane' indicates two substituents on the second carbon of the propane chain: a methoxy group (-OCH3) and a methyl group (-CH3).
Draw the parent chain: Start by drawing a straight chain of three carbon atoms (C-C-C) to represent propane.
Attach the substituents: On the second carbon of the propane chain, attach the methoxy group (-OCH3) and the methyl group (-CH3). Ensure that the carbon has a total of four bonds, as required by the octet rule.
Complete the structure: Add hydrogen atoms to the remaining bonds of the carbon atoms to satisfy the octet rule for each carbon. Verify that the structure matches the molecular formula C5H12O.
