choose the correct answer
C-O in [Fe(CO)6]2+ have stretching bands higher in energy than those in free CO? Due to positively transition metal decreases the electrons toward oxygen. As result of that, bond between oxygen and carbon become stronger and the stretching of bond requires lower frequency. Due to positively transition metal decreases the electrons toward oxygen. As result of that, bond between oxygen and carbon become weaker and the stretching of bond requires higher energy. Due to positively transition...

Carboxylic acids are known to exhibit a higher C=O stretch frequency in the gas phase than in the condensed phases (liquid/solids). Which one of the following statements is the reason for correct: 1. The C=O bond stretch frequency of carboxylic acids depends on overall molecular mobility 2. The C=O bond stretch frequency of carboxylic acids depends on hydrogen bonding 3 .The C=O bond stretch frequency of carboxylic acids depends on temperature 4. The C=O bond stretch frequency of carboxylic acids...

C The boiling point of H,O is much higher than the boiling point of HS. H2O is a molecular compound, while HS is an ionic compound. H2O is a polar molecule, so the attractions between the molecules are stronger than those between nonpolar H2S molecules. H2O has strong hydrogen bonds between its molecules, and HS molecules cannot form hydrogen bonds. The dispersion forces between the H2O molecules are much stronger. d The boiling point of CH,O is much higher than...
