1. Why is it difficult for primary alcohols to form alkenes when treated with potassium hydroxide and ethanol, while secondary and tertiary alcohols do. 2. Why is it difficult for primary alcohols to undergo reaction with acidified water.​

Not sure but hope it helps

hope this

explanation:

covalent bonds

consist of pairs of electrons shared by two atoms, and bind the atoms to fixed orientation and requre high energies to break them

ionic bonds

when two atoms differ considerably in their electronegativity, then one of the atoms will lose its electron to the other atom. this results in a positively charged ion(cation) and a negatively charged ion (anion)

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
