The changes in bond lengths from Me 2O to MeOCH 2X and from MeOCH 2F to MeOCH 2Cl are in good agreement with those calculated ab initio and in radical disagreement with microwave-based values. The effect of halogen is to strengthen all the CH bonds present, especially that lying ...

2-Tolidine (orthotolidine, o-tolidine; not to be confused with o-toluidine) is an organic compound with the chemical formula (C6H4(CH3)NH2)2. Several isomers are known; the 3-tolidine derivative is also important commercially. It is a colorless compound although commercial samples are often ...
Two equatorial planes, Mo(RNC) 4 , mutually adopt an eclipsed form. The Mo O bond length is 1.876(2) and the Mo O Mo angle is constrained to 180°. Complex 2 has a distorted octahedral geometry, in which molybdenum atom is occupied by four isocyanides, O and F atoms....
CH3−C−CH3 (With an O double-bond to the C) (CH3−Li)→ Grignard Reagent: Organolithium compounds can be made to react with ketones or aldehyde and after this reaction, the final product obtained is an alcohol. Tertiary alcohols are formed from ketones. ...

Upon interaction with a Lewis acid v(CO) decreases for the basic CO in all three of the above-mentioned bases, with the order of decrease being (CH3)2C=O C=O moiety, and such an interpretation is borne out by vibrational spectroscopic data. For example, a v(CO) vs. bond order ...
