Why primary alcohol is more reactive when oh bond breaks?
Primary alcohols are more reactive when the hydroxyl (OH) bond breaks due to the stability of the resulting carbocation. When the OH group leaves, it forms a primary carbocation, which is less stable than secondary or tertiary carbocations, leading to a greater tendency to react with nucleophiles or further undergo elimination. Additionally, primary alcohols can readily participate in substitution reactions because they can form a more favorable transition state during the process.
Why do aldehydes and ketones have lower boiling points than their correspending alcohols?
Ketones and aldehydes do not have hydrocarbon atoms which bond to nitrogen or oxygen, individual molecules do not hydrogen bond to each other which makes them have lower boiling points than alcohols.
Where does the extra electron in OH come from?
The extra electron on the OH ion typically comes from another atom or molecule that donates it by forming a chemical bond. This donation allows the OH ion to become stable through achieving a full outer electron shell, following the octet rule in chemistry.
What bond is formed between H plus and OH?
A hydrogen bond is formed between H+ and OH-. Hydrogen bond is a type of dipole-dipole interaction where H+ acts as a hydrogen bond donor and OH- acts as a hydrogen bond acceptor.
Why is the bond angle in a water molecule less than the bond angle methane?
The lone pair - OH bond repulsion in water is greater than the OH bond- OH bond repulsion. In methane all of the bonds are the same so it has perfect tetrahedral symmetry. This is VSEPR theory
Compare the relative polarities of the OH-bond and NH bond?
The OH bond is more polar than the NH bond because oxygen is more electronegative than nitrogen, leading to a greater difference in electronegativity between oxygen and hydrogen. This means the OH bond has a greater separation of charge and greater polarity than the NH bond.
Is OH a covalent or Ionic bond?
OH is a covalent bond. In this case, oxygen and hydrogen share electrons to form a stable molecule.
Why is the bond joining two nucleic acid called phospho di ester bond?
This is because the two OH groups of H3PO4 bond with the OH of the pentol sugars next to the Carbonyl group, so the bond formation resembles esterification.
What type of reaction breaks covalent bonds by the addition of water molecules?
Hydrolysis is the type of reaction that breaks covalent bonds by the addition of water molecules. In hydrolysis, a water molecule is split and its components (H and OH) are added to the atoms within the covalent bond, breaking it apart. This process is commonly involved in the breakdown of large molecules into smaller ones during digestion.
Why is boiling point of glycerol high than hexane?
in glycerol, every molecules are associated together with strong Hydrogen bond which is due to the OH functional group, this H-bond is absent in hexane.Hence it is so, which means more energy is required to break the bond b/w each molecule to release it as vapours
Is sodium hydroxide ionic or covalent bond?
Ionic bond between Na+ and OH- ions.
What type of bond isNaOH?
Ionic bond between Na+ and OH- and a covalent bond in the hydroxide ion bonding hydrogen to oxygen
