Water can form hydrogen bonds because of the polarity of its oxygen hydrogen bonds. In these bonds, oxygen has a partial negative charge and hydrogen has a partial positive charge. Because of this, the partially positive hydrogens on one molecule can form bonds with partially negative oxygen atoms in other water molecules. These intermolecular bonds are hydrogen bonds.
the ability of oxygen to attract electrons more strongly than hydrogen
Water has a slightly negative end and a slightly positive end, it can interact with itself by "sticking" to one another.
large difference in electronegativity of hydrogen and oxygen
More toward oxygen
The electronegativity of bromine is larger than hydrogen, which shifts the location of shared electrons toward bromine.
yes
Combustion, more commonly called "burning," is a chemical reaction between a substance and oxygen. When hydrogen burns, it reacts with oxygen according to the following chemical equation:2H2(g) + O2(g) → 2H2O(l)This tells us that two molecules of diatomic hydrogen gas react with one molecule of diatomic oxygen gas to form two molecules of liquid water. However, because this reaction also generates a large amount of heat, much of the water formed may actually be in the gaseous phase, and hence come off of the reaction as steam rather than liquid water.
This is a trick question, since hydrogen does not form ionic bonds, only covalent bonds (or in some cases, what are called hydrogen bonds). But if you were to ask if hydrogen tends more toward being a donor of electrons (i.e., a metal) or a recipient of electrons (i.e., a non-metal) hydrogen tends to donate electrons. For example in water, H2O, all three atoms share the valence electrons (which is what makes this a covalent bond) however the electrons spend more time in the vicinity of the oxygen atom then they do in the vicinity of the two hydrogen atoms.I am going to make an addition to this answer. The element hydrogen, which is immensely important in organic chemistry, is almost always found as I described it, forming covalent bonds and having a metallic role, tending to donate electrons. However, there are other possible hydrogen compounds, such as lithium hydride (LiH) in which hydrogen does form an ionic bond, and in which it acts as an electron recipient rather than an electron donor. Hydrogen has an electronegativity that is intermediary between metal and non-metal, so it can take on either role. However, it is very rare to encounter lithium hydride, in comparison to compounds such as water, methane, ammonia, etc., in which hydrogen has the characteristics of a metal.

This attraction is called hydrogen bond, what causes higher boyling point in relation to compounds without such bonds
