Fig. 6.1 shows the structural formula of an organic compound. Fig. 6.1 (a) Name any two functional groups presents in the compound. (b) Give the structure of the organic product formed when the compound is reacted with Brz in an inert solvent, (ii) hot concentrated KMnO4, Na solid, (iv) CH3COCI benzenediazonium salt. (c) State the observations made in each of the reactions in each reaction in b​

A dono wat is da anser sori man hehe

(a).

→ Hydroxyl group.

→ Carbon-carbon double bond. ( alkene )

→ Esters.

(c).

(I). A colourless solution : with bromine atoms on cyclo hexene.

or: A white precipitate due to bromine atoms formed on phenol.

(ii). The purple solution turns colourless due to oxidation of the cyclo hexene.

(iii).

Bubbles of a colourless gas ( hydrogen gas ) formed when sodium reacts with the hydroxyl group to form Sodium oate ions.

(iv). Am not sure about my answer.

(v).

A red dye is formed. ( and azo dye is formed due to benzenediazonium salt reacting with phenol ).

it should be p1 v1 = p2 v2

assuming that your periodic table has eighteen columns, you should highlight   the four elements in the third column from the left of the table.

neutral atoms of elements after calcium contain d electrons. the energy of d orbitals of a particular main shell lies between the energy of the s and p orbitals of the next main shell. for example, electrons in the have energy higher than those in the orbital while lower than those of the orbital.

by the aufbau principle, electrons fill orbitals one at a time, starting from those of the lowest energy. the orbital is therefore filled right after orbitals and before orbitals.  

potassium has electron configuration and calcium . the s orbital of a main shell holds a maximum of two electrons. the next element would thus have the electron configuration and satisfy the requirements.

a neutral atom of the element contains three electrons on top of the most recent noble gas element. it should thus be placed in the third column of the periodic table. both scandium and yttrium would satisfy the conditions. an aufbau diagram indicates that the 4f orbital is filled before the 5d. however, it appears that exceptions exists for both lanthanum and actinium. neutral atoms of the two d-block elements also demonstrate the and should be highlighted as well.
