Compare saponification and hydrogenation. select the correct answer below: saponification is a process that produces soap, usually from fats and lye. hydrogenation is a chemical reaction between molecular hydrogen (h2) and another compound or element, usually in the presence of a catalyst. saponification is a chemical reaction between molecular hydrogen (h2) and another compound or element, usually in the presence of a catalyst. hydrogenation is a process that produces soap, usually from fats and lye. saponification is the making of a fat or triacylglycerol from the components of glycerol and fatty acids. hydrogenation of a fat or a triacylglycerol is the reverse process of saponification.

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

the answer is 1 i believe
