It's a feedstock for quite a few products, and it's made in one of three ways: reacting formic acid with ammonia then heating it; reacting carbon monoxide and ammonia; or reacting carbon monoxide and methanol to get methyl formate then performing an aminolysis reaction to get formamide and methanol (which you then react with more carbon monoxide to get more methyl formate...)
Nickel(II) acetate is soluble in water and polar solvents such as alcohols, dimethyl formamide etc.
Drip aqueous ammonia (=>30% in water) into formic acid (=>85%) beware of the fumes. It will precipitate as a white solid with evaporation and cooling. Heat it strongly(>100 celcius ?) the water will be driven of making formamide. Heat it further (>>100 celcius ?) it will form HCN (cyanide! danger!)+ water.
Formamide is the most polar solvent. It has a dipole moment of 3.73 and a dielectric constant of 109. As a comparison, water has a dipole moment of 1.85 and a dielectric constant of 80. The higher the dipole moment value and the dielectric constant, the more polar the solvent. At the opposite, the less polar solvents are hexane, benzene and carbontetrachloride.
Yes, it is slightly soluble. However, your question is not specific enough. Amyl alcohol occurs as several isomers, i.e. same molecular weight (88.1) and formula (C5H12O) but different bond structure between the atoms. The solubility depends on which isomer you are refering to. e.g. n-amyl alcohol (also called 1-pentanol) = 2.7 g per 100g water at 60 deg F iso-amyl alcohol = 2g/100g 2-pentanol = 4 g/100g 3-pentanol = 5.5 g/100g There are a few other isomers as well.

To denature DNA
Through the magic of hydrogen bonding
Denatures the RNA
Examples: propylene glycol, formamide.
Kuta
yes dmf shows antibacterial activity
We can prepare KCN by the reaction of KOH and HCN.Where HCN can be generated by the pyrolysis of formamide.
Dimethyl formamide (DMF) is effective. The polymer swells and the process is slow.
Salt is very soluble in water and soluble in formamide, propylenglycol, glycerine.

we can test moisture of acetone using pyridine or dimethyll formamide in the place of methanol by kf
