Apparently, the first organic compound synthesized in the lab was sucrose. true or false

The correct option is False.

The first organic compound synthesized in the lab was urea. It was synthesized from silver cyanate and ammonium chloride. It is named Wöhler synthesis after the German chemist.

NH₄Cl + AgNCO → H₂NCONH₂

Urea was first synthesized in 1828 and its synthesis was the beginning of modern organic chemistry.

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
