It makes 3 covalent bonds with fluorine, so boron still needs 2 electrons to become stable like a noble gas. So it can receive electrons, which makes it possible for it to be an acid.Is this correct? Logged Babcock_Hall Chemist Sr. Member Posts: 5683 Mole Snacks: +328/-24 Re: Whic...
In carrying out process variant (a), 1 to 2 moles of alkanoyl chloride of the formula (III) and, if appropriate, 1 mole of acid-binding agent are preferably employed per mole of piperidone ketal of the formula (II). Isolation of the reaction products is effected by customary methods. ...
A 1.0-mole sample of krypton gas has a mass of (1) 19 g (2) 36 g (3) 39 g (4) 84 g 3. Standard pressure is equal to (1) 1 atm (2) 1 kPa (3) 273 atm (4) 273 kPa 4. According to the kinetic molecular theory, the molecules of an ideal gas (1) have a strong ...
Preferably, the hydrolysable groups upon hydrolysis yield groups capable of undergoing condensation reactions, such as silanol groups. Examples of hydrolysable groups include halogens such as chlorine, bromine, iodine or fluorine, alkoxy groups —OR′ (wherein R′ represents a lower alkyl group, ...
3.2. Synthesis of the Adsorbent AlxZr(1−x)-UiO-66 series with different Al: (Zr + Al) mole ratios were synthesized by a one-step hydrothermal method. For example, the polytetrafluoroethylene liner (50 mL) was loaded with ZrCl4 (0.163 g, 0.7 mmol), Al3Cl·6H2O (0.0724 g, 0.3 ...
