Popular questions
Is benzoic acid soluble in water?
Only sparingly—about 3 g per liter at room temperature; its solubility increases in hot water and it dissolves readily in many organic solvents.
Is benzoic acid polar?
It has a polar carboxyl group but a nonpolar aromatic ring, so overall it’s only weakly polar; its benzoate salt is much more polar and water‑soluble.
Is benzoic acid a strong acid?
No—it's a weak acid, with a pKa of about 4.2.
What is the melting point of benzoic acid?
About 122–123 °C (251–253 °F).
Is benzoic acid bad for you?
At approved food levels it’s considered safe, with an ADI of 0–5 mg/kg body weight/day; some people may experience irritation or hypersensitivity, and benzene formation in certain acidic drinks is monitored and kept very low.
Is nitrosyl chloride polar?
Yes—NOCl is a polar molecule due to its bent geometry at nitrogen and the differing electronegativities of O and Cl, which produce a net dipole.
(b) in which species (no2cl or no3-) are the n-o bond(s) longer? nitrosyl chloride nitrate ion?
Longer in nitrate (NO3−): its N–O bonds have lower bond order (~1.33) than the N=O double bond in nitrosyl chloride, so they are longer.
How is nitrosyl chloride used?
As the additive E919 it was historically used as a flour treatment/bleaching agent, but this use is now largely discontinued and not authorized in the EU; today it is mainly an industrial chlorinating/nitrosating reagent rather than a common food additive.
Nitrosyl chloride nocl decomposes to nitric oxide and chlorine when heated answer l?
Yes—on heating, 2 NOCl → 2 NO + Cl2, and the decomposition is promoted by heat and light.
Question 6 what is the "axe" description of the nitrosyl chloride molecule?
AX2E1 at the nitrogen center (two bonded atoms and one lone pair), giving trigonal planar electron geometry and a bent molecular shape.
