Question 96 - In infrared spectrum, one of the factors affecting peak location is the mass of the atoms. The stretching frequency of a bond connected to a lighter atom will be greater than the same bond connected to a heavier atom. (a) For halogens like florine (F), chlorine (Cl), bromine (Br), iodine (I) and astatine (At), what is their IUPAC group number? Hint : The proton numbers for F, Cl, Br, I and At are 9, 17, 35, 53 and 85 respectively. (b) For the compounds of H-F, H-Cl, H-Br, H-I and H-At, which one has the lowest stretching frequency and which one has the highest stretching frequency? State the reasons.

Question 95 - The following formula is used as a reference : (analyte signal) / (internal standard signal) = (f-factor) x (concentration of analyte) / (concentration of internal standard). A solution containing 3 mM of analyte and 4 mM of internal standard gave peak signals of 2 and 3 mamps respectively. Another similar solution containing 2 mM of analyte and 1 mM of internal standard gave peak signals of 1 and 4 mamps respectively. Find the average f-factor.

In an existing power plant (phase I) with step up transformers (3nos) with Ynd1 vector group to the 400KV bus bar,an extension power plant (phase II) with transformers (4nos) with Ynd11 vector group >. what are the consequences of such configuration ,please note that % impedance are also differ i.e. 15% & 10.5% the reason was that auxiliary supply interface is at different voltage levels i.e 400v & 6.6KV in phase i and phase II respectively .please advise ! Thank you !
