which of the following would most likely act as a brønsted - lowry acid?\noh⁻\nhcn\nccl₄\nmg(oh)⁺
Answer
Brief Explanations:
A Brønsted - Lowry acid is a substance that can donate a proton ($H^+$). $OH^-$ is a base as it can accept a proton. $CCl_4$ has no ionizable hydrogen for proton - donation. $Mg(OH)^+$ is also more likely to accept a proton to form $Mg(OH)_2$. $HCN$ can donate a proton to form $CN^-$ and is a Brønsted - Lowry acid.
Answer:
B. HCN
