What else can I help you with?
If 4-tert-butylcyclohexanone were reduced with sodium borohydride which isomer of the product 4-tert-butylcyclohexan-1-ol would you expect to predominate?
The reduction of 4-tert-butylcyclohexanone with sodium borohydride would predominantly form the 4-tert-butylcyclohexan-1-ol isomer. This is due to the bulky tert-butyl group favoring the axial position in the chair conformation of the cyclohexane ring, leading to the 1-substituted alcohol as the major product.
What pair of half-reacations would have a negative total reduction potential?
A pair of half-reactions with reduction potentials that differ in sign will result in a negative total reduction potential. For example, a half-reaction with a reduction potential of +0.8 V paired with a half-reaction with a reduction potential of -0.7 V would give a negative total reduction potential (+0.8 V - (-0.7 V) = +1.5 V).
Is the Nernst potential of Sodium achieved during the action potential?
the Nernst potential of Sodium is +60mV. most action potentials do not reach +60mV at peak depoloarization. http://openwetware.org/images/thumb/a/a6/Action-potential.jpg/300px-Action-potential.jpg.png
Is calcium higher than sodium in the electrochemical series?
Yes it is. Calcium atom loses electrons more readily in cell reactions than in reactions with air, water and dilute acids.
What happens to the equilibrium potential of sodium as you decrease the extracellular sodium concentration?
If you decrease the extracellular sodium concentration, the equilibrium potential of sodium shifts towards a more negative value. This is because there is less sodium available to drive the sodium ions into the cell, causing the equilibrium potential to become more negative.
How many moles required to reduce benzophenone to diphenylmethanol using sodium borohydride?
One mole of benzophenone requires one mole of sodium borohydride for reduction to diphenylmethanol.
How is the reduction of ketones with sodium borohydride typically carried out in organic chemistry reactions?
In organic chemistry reactions, the reduction of ketones with sodium borohydride is typically carried out by adding the ketone to a solution of sodium borohydride in a suitable solvent, such as ethanol or methanol. The reaction is usually performed at room temperature or slightly elevated temperatures, and the resulting product is often isolated by simple workup procedures like filtration or evaporation.
Is sodium borohydrate same as sodium borohydride?
Yes, sodium borohydride is the same as sodium borohydride. It is a commonly used reducing agent in organic chemistry.
Is sodium borohydride a reducing agent?
Yes, sodium borohydride is a reducing agent.
Can sodium borohydride reduce ketones?
Yes, sodium borohydride can reduce ketones.
Can sodium borohydride reduce esters?
Yes, sodium borohydride can reduce esters to alcohols.
Does sodium borohydride reduce carboxylic acids?
No, sodium borohydride does not reduce carboxylic acids.
Does sodium borohydride reduce esters?
Yes, sodium borohydride can reduce esters to alcohols.
What is the pKa value of sodium borohydride?
The pKa value of sodium borohydride is approximately 13.
Is sodium borohydride acidic or basic?
Basic because when sodium borohydride is placed in water, the sodium ion and the borohydride ion split, borohydride abstracts a proton (in the form of H+) from a water molecule.
Can sodium borohydride reduce carboxylic acids?
No, sodium borohydride cannot reduce carboxylic acids.
What happens when phenol treated with sodium borohydride?
When phenol is treated with sodium borohydride, a reduction reaction occurs and the oxygen atom in the hydroxyl group of phenol gets reduced to a hydroxide ion. This reaction usually leads to the formation of cyclohexanol as the main product.
