4✔️
6
3

Correct Answer Logic:

Group 15 non-metals: N, P, As, Sb. The weakest $E-E$ bond among non-metals is for nitrogen (N–N is weaker than P–P due to lone pair repulsion in small atoms). Nitrogen has no $d$-orbitals and maximum covalency of 4 (e.g., in $\text{NH}_4^+$, using the lone pair to form a dative bond). Maximum covalency of N $= 4$.

Dairy Food Science and Technology QUESTION #5962

Question 5235

The 'Free Fatty Acid' (FFA) content in milk is used as an indicator of:

Somatic cell count
Lipolytic rancidity — elevated FFAs ($>1.0\;\text{mEq}/100\;\text{g}$ fat) indicate excessive lipase activity from native LPL, psychrotrophic bacteria, or mechanical agitation damage to fat globule membranes✔️
Maillard browning potential
Pasteurization temperature used

Correct Answer Logic:

Short-chain FFAs (butyric C4:0, caproic C6:0, caprylic C8:0) are responsible for lipolytic rancidity (rancid, soapy flavor). Elevated FFA in raw milk ($>1.0\;\text{mEq}/100\;\text{g}$ fat) indicates excessive lipolysis. Mechanical agitation during milking/transport can damage fat globule membranes, exposing fat to LPL.
