Final answer:
None of the listed molecules have an H2OH- group. NH3 is ammonia, ZnC is likely a misprint for a zinc compound, and BF likely refers to a boron-fluorine compound, none of which contain a hydroxide ion.
Step-by-step explanation:
The question seems to be asking which of the given molecules does not have an H2OH- group. Amit H2OH- appears to be a typo or a misprint. Based on the correct chemical terminology, none of the listed molecules (A. NH3, B. ZnC, C. BF, D.
Not specified due to the apparent error) contain the hydroxide ion (OH-), as they are all individual molecules or compounds without associated ions. NH3 is ammonia, ZnC could be an erroneous formula and might refer to a zinc compound, and BF probably refers to a boron-fluorine compound, possibly meant to be BF3, which is boron trifluoride. None of these examples include a hydroxide group.
