Use the chain rule, u = 3x-2dy/dx = dy/du du/dxdy/du = d(u^1/2)/du = 1/2 u ^-1/2power down and minus 1du/dx = 3constants =0so, dy/dx = 3 1/2 (3x-2)^-1/2= 3/2 (3x-2)^-1/2

1.Butanoic acid has stronger intermolecular forces (hydrogen bonding) because it has two highly electronegative oxygen atoms in its structure, whereas butan-1-ol has only one. Therefore t...
