2014年6月10日 · From electronegativity considerations, both carbon and bromine have very similar electronegativities - 2.5 and 2.8 - respectively. Nonetheless, I am told that such a bond would be polar. We generally classify bond between atoms with EN differences < 0.5 as non-polar; why would C-Br be an exception? What is your source for this view?

2019年9月1日 · CBr2H2 = dibromomethane. I can't easily draw the structure here, but do look it up. You will see that it is asymmetrical and has a tetrahedral geometry, so it is polar, but does NOT exhibit hydrogen bonding. Also, the polarity is less than that for methanol. So, it will be soluble/miscible in water, but much less so than methanol.
