In a water molecule, the electrons are localized around the oxygen atom as it is much more electronegative than the hydrogen atom. The presence of a lone pair of electrons in the oxygen atom causes the water molecule to have a bent shape as per the Valence shell electron pair repulsion theo...
(M4) hydrogen bonding is stronger than London forces and requires more energy to break(and results in a higher boiling temperature)6(b) An explanation that makes reference to the following points:(M1) oxygen is more electronegative than hydrogen andcarbon(M2) which results in a polar bond ...
Oxygen is more electronegative than carbon, so it holds a partial negative charge. This is also true between the hydrogen-oxygen bonds in water, so the partial charges between water and carbon dioxide interact more than other gases interact with water....
The OH bond in is polar because: (a) it is an ionic bond. (b) oxygen is much more electronegative than hydrogen. (c) oxygen occupies more space than hydrogen. (d) hydrogen is much more electronegative than oxygen. (e) it is a hydrogen bond. ...
Which compound has the strongest hydrogen bonding between its molecules? What is the least electronegative element? Does oxygen have a higher electronegativity than hydrogen? Which element on the periodic table is the most electronegative? What is the relationship between electronegativity and the ionic ...
Why alkyl carbocation is more stable than vinyl carbocation? CH2=CH sp-hybrid carbon sp-hybrid carbon ismore electronegative Postive charge is present on electropostive carbon. Hence alkyl carbocation is always more stable than vinyl carbocation. ...
The clear answer is PTFE. That's kind of indisputable. But it's pertinent to ask why. Fluorine is heavier than hydrogen and thus PTFE strands might be assumed to be higher molecular weight than LDPE. But that's neither here nor there. The real reason is mass and electron density. The ...
In 1923, Brönsted and Lowry independently described acids as substances which enhance the hydrogen ion concentration (proton-donors) and bases as substances which diminish the hydrogen ion concentration (proton-acceptors; in water, the most important proton-acceptor is the OH¯ ion) This substance...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
Increased cardiovascular risk is linked to a rise in the proportion of the electronegative LDL form (LDL(-)) present in the blood. Laboratory experiments have revealed that LDL(-) displays pro-atherogenic attributes, such as a heightened tendency towards aggregation, the capacity to stimulate ...
